Cortus 的 compact 32-bit RISC
Embedded.com 的新聞 [French startup offers compact 32-bit RISC] 介紹 [Cortus] 公司最新的 processor 產品 [APS32]。在新聞稿提到：-
The company, founded in 2005 and which changed its name from Advanced Processing Solutions to Cortus, claimed on its website that it can not only produce small and power efficient cores, but that they can also support out of order instruction completion; something associated with much larger PC microprocessors. According to an entry at the Design & Reuse website semiconductor intellectual property catalog the APS32 requires only 7,000 gates and consumes 18-microwatts per megahertz.
The APS2 has 32-bit fixed-length instructions and there is a set of peripherals including; UARTs, memory interfaces, cache memory controller, configurable interrupt controller, general purpose I/O. AMBA AHB and APB on-chip bus wrappers are in development the company said.
It is not clear whether the design has been taken to silicon but the datasheet shows it benchmarked with Actel and Xilinx FPGAs and in 0.13-micron CMOS from TSMC using Artisan libraries for implementation. In the last case the APS2 core should occupy 0.07 square millimeters and operate at up 330-MHz clock frequency.
“The CPU itself is no bigger than the 8-bit CPU core in a 8051 or a 6811 microcontroller,” the company said. The core is suitable for implementation within a field programmable gate array and the company is a member of an Actel partnership program.
Cortus supplies a free port of the GNU C and C++ compiler and toolchain. The toolchain runs on Linux, Windows XP and most Unix varieties, the company said.
