(eng): The article describes instruction set extensions for a variant of multi-threading called micro-threading for the LEON3 SPARCv8 processor. An architecture of the developed processor is presented and its key blocks described - cache controller, register file, thread scheduler. The processor has been implemented in a Xilinx Virtex2Pro and Virtex5 FPGAs. The extensions are evaluated in terms of extra resources needed, and the overall performance of the developed processor is shown for a simple DSP computation typical for embedded systems.
