流水线操作处理器和控制系统

Pipeline operation processor and control system

Abstract

公开一种流水线操作处理器和控制系统。流水线操作处理器(2)包括:流水线处理单元(2b);和指令插入控制器(2a),其在请求对操作存储器(4)的访问时插入指令,并通过参照级的控制信息校正控制信息。当控制程序(4a)正在执行时,在接收到请求对所述操作存储器(4)进行访问的访问请求指令时,所述指令插入控制器从所述指令解码单元(2b2)插入NOP指令,代替所述访问请求指令。在流水线处理单元(2b)不执行操作时执行所述访问请求指令,并随后,继续所述流水线处理。
The invention discloses a pipeline operation processor and control system. The pipeline operation processor comprises a pipeline processing unit and an instruction insertion controller which inserts an instruction when access to an operation memory is requested, and corrects control information by reference to control information of stages. When a control program is in execution, on receiving an access request instruction requesting for access to the operation memory, the instruction insertion controller inserts an NOP instruction from the instruction decoding unit in place of the access request instruction. The access request instruction is executed while the pipeline processing unit executes no operation, and subsequently, the pipeline processing is continued.
