In the design of next-generation distributed and high-performance computing systems, Reconfigurable Processing Elements (RPEs) such as FPGAs and multi-core heterogeneous computers will play an important role. FPGAs are well-known for their programmability, power efficiency, reasonably high performance, functional flexibility, and their scalability. However, proper virtualization schemes at higher...
This paper presents an adaptable softcore chip multiprocessor (CMP). The processor instruction set architecture (ISA) is based on the VEX ISA. The issue-width of the processor can be adjusted at run-time (before an application starts). The processor has eight 2-issue cores that can run independently from each other. If not in use, each core can be taken to a lower power mode by gating off its source...
In this paper, we present a very long instruction word (VLIW) softcore processor implemented in an FPGA. The processor instruction set architecture (ISA) is based on the VEX ISA. The issue-width of the processor can be dynamically adjusted. The processor has two 2-issue cores, which can be run independently. If not in use, each core can be taken to a lower power mode by gating off the source clock...
