A multimedia mobile processor HCgorilla developed for ubiquitous network was built in Java CPU, cipher logic, and floating point arithmetic units. HCgorilla needed instruction scheduling, because the execution stage of HCgorilla had integer and floating point arithmetic pipelines that were physically separated and had different latencies. We describe, in this paper, the solution of this issue and the improvement of HCgorilla. Specifically, the execution stage is made a multifunctional hardware unit by merging the physical separation of arithmetic pipelines. Then, the multifunctional execution unit is wave-pipelined. Multifunctional wave-pipelines realize wide-range dynamic ILP (instruction level parallelism) at a rate higher than regular superscalar architecture. |
