The host-multi-SIMD chip multiprocessor (CMP) architecture has been proved to be an efficient architecture for high performance signal processing which explores both task level parallelism by multi-core processing and data level parallelism by SIMD processors. Different from the cache-based memory subsystem in most general purpose processors, this architecture uses on-chip scratchpad memory (SPM)...
The host-SIMD style heterogeneous multi-processor architecture offers high computing performance and user friendly programmability. It explores both task level parallelism and data level parallelism by the on-chip multiple SIMD coprocessors. For embedded DSP applications with predictable computing feature, this architecture can be further optimized for performance, implementation cost and power consumption...
As the use of FPGAs increases, the importance of highly optimized processors for FPGAs will increase. In this paper we present the microarchitecture of a soft microprocessor core optimized for the Virtex-4 architecture. The core can operate at 357 MHz, which is significantly faster than Xilinxpsila Microblaze architecture on the same FPGA. At this frequency it is necessary to keep the logic complexity...
