CAST provides digital semiconductor intellectual property cores and subsystems. Our proven, high-value IP line includes:

 

  • low-power, high-performance processors and microcontrollers;
  • hardware compression and decompression for video, images, and data; and
  • popular interconnects, peripherals, and encryption cores.

 

CAST customers benefit from the rigorous product development and packaging standards we’ve developed over nearly 25 years of operation, and from our equally refined IP business and licensing practices. Our sales, support, and engineering staff has helped hundreds of customers—from unknown start-ups to the world’s most recognized IDMs—successfully develop and ship millions of product units.

 

Highlights in our diverse product line include GZIP cores fast enough for firmware decompression; the most production-ready CAN FD controller available; one of the first SHA-3 encryption cores; 32-bit processors with the greatest code density in the industry; and the oldest yet most modern family of 8051-compatible microcontrollers.

Services

IP Integration

Decrease time to market while improving design quality with CAST’s IP integration services. We can combine any of the cores we offer with other IP, PHYs, drivers, and more to deliver complete systems or subsystems optimized to your specific requirements.

 

We also provide complete, pre-integrated AMBA-based systems and subsystems ready for customization and deployment.

IP Cores

Microcontrollers and Processors

Drive embedded and IoT systems, sensor subsystems, and more with compact, low-power, 32-bit BA2x™ Family processors or small, versatile, 8051-compatible microcontrollers.

 

The BA2 instruction set enables great code density, significantly reducing the size of the memory devices needed for these processors. The BA2x processor family includes features that help differentiate your products from everyone else’s—like an ultra-low-power PipelineZero™ architecture—while class-leading performance and area specs ensure competitive results.

 

Various preconfigured BA2 processors bundle features and peripherals to target deeply embedded systems through application processors running Android or Linux. All include the BeyondStudio™ IDE for quick programming, and reference designs, evaluation systems, and integration services are available.

 

The 8051s from CAST offer small size, easy integration and programming, and relatively fast performance. Whether to run simple applications or to offload a main processor in larger SoCs, these soft MCS®51-compatible cores are among the most feature-rich and customer-proven available anywhere.

 

They offer configurable CPUs and bundled peripherals, 8-bit area and power savings, easy development and test, proven reliability, and royalty-free value.

Video and Image Compression

The Video and Image Compression IP family provides a range of hardware encoders and decoders for JPEG, AVC/H.264, and HEVC/H.265 video. They offer:

 

  • Scalable performance, supporting resolutions beyond Ultra-High Definition (UHD) and/or ultra-high frame rates.
  • Extremely small silicon footprints, enabling low-power and economical implementations in FPGAs and ASICs.
  • Excellent video quality, even for ultra-low-latency, and/or low-bit-rate video streaming.

 

Each encoder and decoder satisfies particular needs for performance, power consumption, and silicon area, and offers smart trade-offs of compression degree and quality. Included are:

 

JPEG and Motion JPEG Encoders and Decoders, in Baseline and Extended (12-bit) variations, offering an economical yet high-quality alternative for moderate levels of video compression,

 

H.264/AVC Video Encoders and Decoders, supporting different profiles and featuring the lowest power consumption and smallest silicon area compared to competitive cores, and

 

An H.265/HEVC Decoder with versatile support for multiple profiles and video system characteristics.

 

CAST is one of the longest-running providers of image and video compression IP cores, with hundreds of successful customers shipping millions of media products, beginning in 1998.

Data Compression

The ZipAccel™ Cores enable hardware lossless data compression that is unmatched in performance, low energy consumption, flexibility, and ease of integration and use.

 

The ZipAccel-C Compression Core implements a lossless data compression engine that complies with the Deflate, GZIP, and ZLIB compression standards. The ZipAccel-D Decompression Core implements decompression for the same standards. A ZipAccel-C Reference Design Board offers is ready for evaluation or initial system design.

 

The ZipAccel-C Compression Core’s flexible architecture enables fine-tuning of its efficiency, throughput, and latency to match application requirements. Throughputs over 100 Gbps are feasible even in low-cost FPGAs; latency can be as small as a few tens of clock cycles.

 

The ZipAccel-D Decompression Core features fast processing, with low latency and high throughput. On average the core outputs three bytes of decompressed data per clock cycle, providing over 15Gbps in a typical 40nm technology. Designers can scale the throughput further by instantiating the core multiple times to achieve throughput rates exceeding 100Gbps. The latency is in the order of few tens of clock cycles for blocks coded with static Huffman tables, and typically less than 2,000 cycles for blocks encoded with dynamic Huffman tables.

 

Interconnects and Interfaces

Readily implement standard interfaces for automotive, avionics, industrial, and other applications.

 

The Automotive Bus IP cores from CAST feature the most production-proven CAN 2.0/FD controller available anywhere. It is backed with verification IP (VIP) and a ready-to-run hardware reference design board.

 

Automotive Bus cores also include a LIN master/slave controller, SENT/SAE J2716 transmitter/receiver controller for sensor connections, and an IEEE 802.1AS Hardware Protocol Stack for time-sensitive networking via Automotive Ethernet.
