摘要
In a computing system where a plurality of processing units may execute a shared code independently, it is necessary to address data issues related to execution of the shared code and separate data. According to various embodiments disclosed herein, the per-processing unit data can be efficiently addressed in a program counter relative mode where data is accessed using a data offset value for each processing unit when the data blocks are positioned at spaces of a predetermined offset value. Further, the per-processing unit of common code in different virtual addresses is mapped to a common physical address. As a result, while each of the processing units access the exact same instruction code in physical memory it accesses a different area in memory for manipulation of data.
