Xilinx Inc. has announced that its PicoBlaze 8-bit microcontroller reference design now includes support for the company's Virtex-II series of FPGAs and CoolRunner-II CPLDs, giving customers access to microcontroller solutions that utilize the company's complete range of programmable products.

By expanding support to include CoolRunner-II CPLDs and Virtex-II Series FPGAs, our users now have access to microcontroller solutions meeting even lower cost targets and higher performance," claims Per Holmberg, director of programmable systems marketing at Xilinx.

All of the PicoBlaze reference designs support 49 different 16- to 18-bit instructions, 8 to 32 general-purpose 8-bit registers, 256 directly and indirectly addressable ports, reset, and a maskable interrupt.

The PicoBlaze for CoolRunner-II solution includes a generic C cross assembler and the VHDL source code that designers can customize for their specific needs. The CoolRunner-II version occupies only 107 macrocells and can be implemented in a XC2C128 (128-macrocell) device.

In addition, the solution can be optimized to fit into a XC2C64 (64-macrocell) device. It can be implemented and demonstrated using the recently released CoolRunner-II Design Kit.

The PicoBlaze for Spartan-IIE occupies 76 Spartan-IIE slices. Implemented in the XC2S300E FPGA, the design is claimed to consume <2 percent of the device resources. The PicoBlaze for Virtex-II Series FPGAs reaches performance levels of up to 55 MIPS.

The PicoBlaze reference designs supporting Virtex/Virtex-E, Spartan-II/E, Virtex-II series FPGAs, and CoolRunner-II CPLDs are now available to download free of charge at
