The Research on Memory-Level Parallelism Execution Model in EPIC Architecture
Deng Rang · Chinese Journal of Computers · 2007
This paper presents an instruction Optimized Lock-Step execution Model(OLSM)and builds a memory hierarchy which can embody the essence of this model.In OLSM EPIC micro-processor,instruction can be executed out-of-order,so shortcoming of tradition VLIW lock-step execution is resolved.OLSM can make use of the abundance computation and memory resources to hide memory access latency and improve Memory Level Parallelism(MLP)at best.
