Abstract(in English) | We aim to develop a cost-effective RISC-V scalar processor of pipelining for FPGAs. In this report, we try to implement an efficient instruction fetch unit. We clarify the problem of an instruction fetch unit in the processor that support the RISC-V compressed instructions. To solve the problem, we propose two instruction fetch units. We implement the proposed fetch units and evaluate their performance, hardware resources, and operating frequency. Through the evaluation, we show that the proposed unit with a compressed cache is the best and achieves 21.8% better fetch performance than a baseline architecture. |
