Heterogeneous computing system configured to adaptively control cache coherency

摘要

A heterogeneous computing system includes a first processor and a second processor that are heterogeneous. The second processor is configured to sequentially execute a plurality of kernels offloaded from the first processor. A coherency controller is configured to classify each of the plurality of kernels into one of a first group and a second group, based on attributes of instructions included in each of the plurality of kernels before the plurality of kernels are executed and is further configured to reclassify one of the plurality of kernels from the second group to the first group based on a transaction generated between the first processor and the second processor during execution of the one of the plurality of kernels.
