Cast offers IP (intellectual-property) cores for general-purpose 8-, 16-, and 32-bit processors. A configurable 8051 core executes instructions with one clock per cycle. Additional cores include 8-bit Z80 and 16-bit 68000- and 80186EB-compatible devices. Cast's 32-bit APS cores target embedded systems needing more performance than an 8051 can offer. They require as few as 7000 gates, perform at 0.6 Dhrystone MIPS/MHz, and use as little as 18 µW/MHz of power. A coprocessor architecture enables performance improvement for specific applications, and an ASP-DSP coprocessor is available.
