Novatek Reduces TV Boot Time with Data Decompression IP Core from CAST

Novatek Microelectronics Corp., a customer of semiconductor IP provider CAST, Inc., has applied a data decompression IP core to achieve a major consumer benefit: significantly reduced start-up delay in digital televisions.

Consumers don’t like to wait when they turn on a television set. Much of this start-up or “boot time” delay is due to the time required to read the initial firmware code out of the relatively slow, non-volatile, flash memory where it is stored. Novatek’s innovation dramatically reduces this boot time by storing a much smaller, compressed version of the firmware, and using a fast hardware decompression engine obtained from CAST to rapidly decompress the code during boot.

Novatek Logo & CAST IP purchase news
The ZipAccel-D GUNZIP/ZLIB/Inflate Data Decompression IP Core available from CAST is a hardware decompression engine with remarkably low latency and high throughput. Novatek successfully used its initial single-use license for the core in one of its highly integrated, programmable, system-on-chip (SoC) products targeted to digital TV manufactuers, then upgraded to a multi-use license to apply the technology to additional chipset products. The approach not only increases consumer satisfaction with a shorter boot time, but also reduces system costs by enabling the use of smaller, less expensive memory devices.

GZIP IP product icon
“The GUNZIP core from CAST was relatively easy to integrate, functions and performs well, and gives our DTV chipsets a distinct competitive advantage,” said Daniel Ping, television products director for Novatek. “The core itself is well-designed and packaged, and CAST’s excellent technical service and support has helped us meet or exceed our project schedules.”

The decompression engine Novatek licensed is part of the ZipAccel™ family of data compression IP CAST sources from Sandgate Technologies. A compression engine and complete PCIe Compression Reference Design Kit are also available. Other CAST customers have used ZipAccel engines to reduce boot time and energy consumption in a variety of application areas; read about this approach in the CAST white paper Firmware Compression for Lower Energy and Faster Boot in IoT Devices.

New Tiny 80251 Beats Other Low-Power, High-Capability Microcontroller Options.
Available from CAST, Inc. this fast, easy-to-program, peripherals-loaded 16- and 32-bit controller needs less silicon area and code memory space and fewer memory operations than most 8-bit 8051s or 32-bit RISC processors

Nuremberg — Embedded World, February 23 2016

Semiconductor intellectual property provider CAST, Inc. today introduced a new microcontroller in its 8051-compatible IP line, the T80251XC3 Tiny, Configurable, 16-bit 80251 Microcontroller IP Core.

The new MCU is optimized to provide the 16- and 32-bit data processing capabilities of the 80251 architecture in less than 13K gates, a silicon area no larger than a fast 8-bit 8051 and much smaller than a typical 32-bit processor. It further offers system-wide cost and energy savings through greater code density for 16-bit processing—enabling the use of smaller firmware memory units—and a CISC design using more complex addressing modes that slashes the number of power-consuming load-store operations typically comprising 20–25% of the code for 32-bit RISC designs.

In addition to smaller size and less cost, the Tiny 80251 offers advantages that make it an excellent match for many modern applications. Sourced from partner Silesia Devices—one of the most experienced 8051 IP development teams in the world—the design is carefully optimized for performance and achieves a Dhrystone benchmark score of 0.1455 DMIPS/MHz (using the Keil compiler). A fully configurable set of proven peripherals is included and the 8051 ecosystem is mature, simplifying and reducing the risk of developing systems using the T80251XC3. Finally, the royalty-free licensing fees for the Tiny 80251 are likely much lower than for other advanced MCUs, further enabling low product pricing in IoT and similarly competitive markets.

Visitors to Embedded World and DVCon (San Jose) are welcome to stop by the CAST booth for more information.

CAST Introduces H.264 Video Over IP Subsystem to Simplify Video Streaming Product Development

Woodcliff Lake, NJ — October 11, 2013 — Semiconductor intellectual property provider CAST, Inc. has released a reusable subsystem and suite of hardware reference designs that make it easier to build video streaming into mobile and other products.

The new H264OIP-HDE Subsystem integrates three IP cores available from CAST: the H.264 High Profile Video Encoder (H264-HP-E) core for high-quality video compression, and the RTP and UDP/IP hardware stacks for encapsulating video for Internet Protocol transmission. Flexible video, memory, and network interfaces simplify system integration, and optional logic blocks enable standalone, processor-free subsystem operation. Available hardware reference design systems provide a turnkey jumpstart to streaming system development.

The new subsystem is an especially competitive solution for low-latency applications that demand minimal video delay. The advanced rate control capabilities of the H.264 encoder core, the near-zero latency of the hardware RTP/UDPIP encapsulation, and the ability to directly process the uncompressed video stream as presented by the capturing device together enable the H264OIP-HDE Subsystem to stream video with ultra-low—sub-5ns—latency. Furthermore, the subsystem’s dedicated hardware implementation means it consumes significantly less energy than any similar software-based alternative.

“This new video over IP subsystem makes the superior H.264 compression we offer drop-in ready for high-performance, low-latency, low-energy, video streaming over Ethernet or Wi-Fi,” said Nikos Zervas, chief operating officer for CAST. “Completing the solution are FPGA reference designs for turnkey HDMI- or DVI-to-Ethernet streaming in hardware, and customization services through which we can deliver a pre-packaged and fully-verified combination of any video-in or network controllers a customer requires.”

Reference designs for the streaming subsystem are available now for the Altera® Stratix® IV and Arria® V families, and the Xilinx® Kintex®-7 line. These include the CAST and other essential IP cores implemented in an FPGA, plus the necessary interfaces, memory, drivers, and software.

CAST’s IP customization services are available to integrate the Subsystem with a variety of memory controllers, input video interfaces (e.g., DVI, HDMI, MIPI-CSI, or SDI), and IP-based MAC controllers (e.g., Ethernet or 802.11 Wi-Fi). Other options include multiple video channels, different video preprocessing modules, or different compression algorithms (e.g., JPEG or JPEG 2000), and mapping the subsystem to different FPGA platforms.
The H264OIP-HDE Subsystem in RTL for ASICs or netlists for FPGAs is available now, including the H.264 Encoder Core (sourced from Alma Technologies SA) and the CAST RTP and UDP/IP Cores, other essential functions, complete documentation, and more.

Low-Power BA21 Processor Core Brings 32-bit Benefits to Embedded Microcontroller Applications

Design Automation Conference — Austin, Texas, USA — June 3, 2013 — Processor intellectual property company Beyond Semiconductor and IP provider CAST, Inc. today unveiled the ultra-low power BA21™ embedded processor, further expanding the BA2x™ family of 32-bit processor cores.

The BA21 Low-Power Embedded Processor delivers 32-bit processing capability in a small, energy-efficient package, achieving 2.5 CoreMarks, operating up to 125 MHz, and needing under 10K gates (with a 65nm process). Its two-stage pipelined design is optimized for low power consumption in deeply embedded applications such as wireless communications or mixed-signal control. It offers a powerful step up from 8-bit microcontrollers used for such applications, as well as being a more efficient choice over larger general-purpose system processors.

“The world’s rush towards big data accessed anywhere requires devices that can capture, process, and analyze information within severe power budgets, and this can only be achieved through highly efficient hardware designs,” said Matjaž Breskvar, chief executive officer of Beyond Semiconductor. “To address such needs, this new BA21 core applies unmatched design efficiency to the most area- and power-sensitive end of the processor spectrum, doing more work in less silicon and using less energy than any comparable 8-, 16-, or 32-bit processor. It’s the perfect fit for the next generation of intelligent sensors, deeply embedded devices, or as a helper in complex SoCs.”

Energy consumption levels for a BA21-based system can be as low or lower than those possible with any competing processor thanks to the small silicon footprint, extreme code density, and lower memory demand of the BA2™ instruction set architecture (ISA). Effective power management functions such as clock gating of unused units and hardware or software controller dynamic frequency scaling further reduce energy usage. Options for expanded capabilities include floating point functions, hardware multiplication/divide, vectored interrupt control for fast response, and a memory protection unit.

“The royalty-free BA2x family has a growing reputation for offering a smart, technically-competitive IP choice in a processor market dominated by a single provider,” said Nikos Zervas, vice president for marketing of CAST. “CAST has long been a leader in 8051 applications and for last few years our customers have been asking for greater capabilities for more advanced designs. The BA21 is the perfect answer to that request: it offers great appeal to designers seeking to differentiate their products through better performance, lower energy usage, quick development, and a lower price point.”

The BA21 comes bundled with a customizable set of peripherals and functions. It expands the BA2x Family of 32-bit processors, complementing the mid-range BA22™ and the higher-end BA25™ full application processor. All support the BA2 instruction set architecture, which provides efficient operation and extreme code density for greater system-wide power savings.

Product packages include the Eclipse- and GNU-based BeyondStudio™ tool set to facilitate software development. A complete BA21 system board is available for easy evaluation or as a quick software development platform.

Already in use by early customers, the BA21 Low-Power Embedded Processor Core is available immediately, and will be highlighted in CAST’s booth at DAC (#2024).

BA2x, BA21, BA22, BA25, and BeyondStudio are trademarks of Beyond Semiconductor. All other trademarks are the property of their respective owners.

Ultra-Low Latency H.264 Video Encoding Now Available from CAST

Woodcliff Lake, NJ — May 16, 2013 — The H.264 video encoder IP cores available from semiconductor intellectual property provider CAST, Inc. now feature an option for ultra-low latency video encoding. This enables near-real time video transmission for streaming and wireless video applications, especially when coupled with CAST’s hardware stacks for fast, processor-less video processing.

Low Latency and Video Encoding
Latency is the delay incurred in processing and transmitting live video. Having a negligible delay of under 150 milliseconds (4.5 frames for 30 frames per second video) is critical in applications involving human interaction—such as video conferencing, remote surgery, online gaming, or high-value surveillance—and an even lower delay of 30ms (one frame for 30fps) or less is essential for many automotive, industrial, and medical systems.
While total latency is determined by the end-to-end process of video capture, encoding, transmission, decoding, and display, it is the encoding that typically has the most critical role. An ultra-low latency encoder needs to meet the target bit rate (e.g. 7 Mbps) over a small period of time (e.g. 1 frame). This allows the decoder to start the decoding process after buffering just a small amount of the compressed stream, and provides guarantees that the decoder buffer will not underflow throughout video playback.

Achieving Ultra-Low Latency Video Encoding
The H.264 video encoder cores available from CAST have always allowed a designer to regulate latency down to a few frames through a sophisticated rate control algorithm. The intra-only versions of these encoders can now go further, giving designers the ability to regulate latency at a deep sub-frame level. This enables latencies under 20ms for 30 frames per second video, and under 10ms for 60fps.
The sub-frame rate control feature for ultra-low latency is now a standard part of the intra-only version video encoder cores and available from CAST worldwide. These new ultra-low latency intra-only encoders support the Baseline, Main, and High Profiles of the H.264 standard (ISO/IEC 14496-10/ITU-T) and are sourced from technology partner Alma Technologies.

Video Streaming Hardware Stacks
Processing the encoded video stream for transmission also impacts end-to-end latency. Most video systems rely on a central system processor to handle this, but for many applications there is a quicker method.
Dedicated hardware stacks can more efficiently transmit video over specific channels. CAST has developed two such stacks that can prepare and transmit a video stream without the assistance of a processor: the UDP/IP Hardware Protocol Stack Core handles video transmission over an Ethernet LAN or similar Internet Protocol media, and the Hardware RTP Stack Core encapsulates H.264/NAL streams to Real-time Transport Protocol packets that are compliant with RFC 3894 and RFC 6184.
