Woodcliff Lake, NJ, February 17, 2009 — Silicon Intellectual Property (IP) provider CAST, Inc. today released a new member of its 8051-compatible processor family, the R8051XC2 IP core. Running 12.1 times faster than the original 8051 chip, the new core is the fastest CAST has offered, and the company believes it to be the fastest 8-bit 8051 IP available anywhere.
"The 8051 is the world's most popular microcontroller, with rich and varied roles even in today's advanced products," said Hal Barbour, president of CAST. "We've been delivering 8051 IP since 1997 and know the market well: nothing is as fast, power-efficient, flexible, and user-friendly as this R8051XC2."
Developed for ASIC or FPGA system-on-chip designs, the new 8051 core has a single-clock architecture that uses an average of 2.12 cycles per instruction. This high-speed performance also reduces power consumption: using fewer cycles for the same operation makes a 90 nm ASIC implementation of the new core 10% more efficient than CAST's previously best 8051. (See www.cast-inc.com/cores/r8051xc2 for details, and more implementation examples.)
The new core is highly configurable, with variations covering the 8051 spectrum from full-featured processors with multiple peripherals to streamlined controllers doing specific jobs. Customers can purchase the fully-configurable version to cover all their 8051 needs, prepackaged versions that mimic off-the-shelf chips, or a custom set of features and capabilities for their specific requirements. Full MCS51 instruction set compatibility, a native on-chip debugging option, and support by Keil's C51 development tools ensure quick and successful R8051XC2 system development.
Founded and headquartered in San Jose, California, S2C is the leading total solution provider in facilitating systems to chip innovations. S2C has four solutions for system-on-chip (SoC) development:
S2C's value proposition is our highly qualified engineering team and customer-focused sales force that understands our customers' commercial needs in SoC development. S2C's unique FPGA-based electronic system level (ESL) solution, using our patented TAI IP technology, enables designers employ silicon IP to quickly assemble SoC prototypes on FPGA easily and securely, thereby enabling customers to start software development, typically the long pole item in development schedules, immediately. Combining rapid prototyping methodologies with a comprehensive portfolio of silicon IP and advanced design solutions, S2C can reduce the SoC design cycle by up to nine months.
S2C currently has 3 direct offices located in Shanghai, Beijing and Shenzhen to meet the demand for accelerated SoC design activities in China. S2C is also the organizer of the annual SoCIP seminar and exhibition in China, which brings SoC designers/professionals from the Asia-Pacific region together with international silicon IP and SoC solution vendors.
