Title:
第１の処理回路と第２の処理回路との間で作業負荷を切り替えるためのデータ処理装置および方法
Document Type and Number:
Japanese Patent JP5823987
Kind Code:
B2
Abstract:
A data processing apparatus has first processing circuitry which is architecturally compatible with second processing circuitry, but with the first processing circuitry being miero-architccturally different from the second processing circuitry. A switch controller performs a handover operation to transfer performance of the workload from source processing circuitry to destination processing circuitry, with the source processing circuitry being one of the first and second processing circuitry and the destination processing circuitry being the other of the first and second processing circuitry. During the handover operation, the switch controller causes the source processing circuitry to makes it current architectural state available to the destination processing circuitry and is necessary for the destination processing circuitry to successfully lake over performance of the workload from the source processing circuitry. The switch controller masks predetermined processor specific configuration information such that the transfer of the workload is transparent to that operating system.
