Outline of Final Research Achievements

In this research, we designed and verified our realistic microarchitecture of CoreSymphony in hardware description language which enables efficient cooperative core features on multi-core processors. In other words, we reduced the required hardware cost for CoreSymphony processors using sophisticated microarchitecture techniques. Moreover, in order to develop an FPGA (field-programmable gate array) board for computer architecture research, high-speed serial communication between FPGA boards with serial ATA cables is evaluated and confirmed its high data bandwidth and we designed original FPGA board with this high-speed serial communication, FPGA, and DRAM chip.
