This paper describes instruction set extensions for a variant of multi-threading called micro-threading for the LEON3 SPARCv8 processor. We show an architecture of the developed processor and its key blocks - cache controller, register file, thread scheduler. The processor has been implemented in a Xilinx Virtex2Pro FPGA. The extensions are evaluated in terms of extra resources needed, and the overall...
This paper presents a stack based, 4 bit instruction set soft core, named ZtCore. Z stands for Zero waste, which means it possesses high code density and efficient run time behavior. T stands for tiny, which means its resources consumption is low. In this paper, the architecture of ZtCore is described, as well as its implementation. Meanwhile, some evaluations about its performance are presented,...
This paper explores the advantages of adding an MMX extension to the MicroBlaze (MB) soft processor,through its FSL ports. The implemented MMX unit is described in detail, were emphasis has been done in parallelizing the instruction execution. The propagation delays and FPGA resources consumed obtained for the different blocks during the synthesis phase for a Virtex-II target device are also shown...
