Data processing apparatus and data processing method for performing pipeline processing based on RISC architecture

摘要

A data processing apparatus has a data memory, and a non-stalling write-back control circuit. The non-stalling write-back control circuit performs control so that, if a write instruction for writing data to the data memory encounters a write failure due to a cache miss or memory access contention, any succeeding instruction is allowed to continue to execute provided that the succeeding instruction is not a memory access instruction.
