PicoBlaze microcontroller gets expanded support

12 February 2003 DSP, Micros & Memory

Xilinx has expanded device support for its free PicoBlaze 8-bit microcontroller reference design to include Virtex-II Series FPGAs and CoolRunner-II CPLDs. The PicoBlaze reference design is fully customisable and is an ideal solution for quickly building simple, flexible, and highly cost-effective embedded designs using programmable logic, claims 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 customise for specific needs.

The PicoBlaze for Spartan-IIE occupies 76 Spartan-IIE slices.

The PicoBlaze for Virtex-II Series FPGAs reaches performance levels of up to 55 MIPS.

The PicoBlaze User Web Resource is at www.xilinx.com/ipcenter/processor_central/picoblaze/picoblaze_user_resources.htm
