专利汇可以提供Instruction prefetching device forecasting address to be branched专利检索,专利查询,专利分析的服务。并且PURPOSE:To execute a branch instruction without time loss in an information processor by registering branch information including an address to be branched for the branch instruction in a branch history table and by forecasting the address to be branched basing on the past result. CONSTITUTION:A branch history table BHT410 stores information specifying the address of a branch instruction and a branch enabling/disabling flag and an address to be branched as the forecast of the execution of said branch instruction so as to form a pair of information. The contents of an instruction address register 411 index the table BHT410 and the BHT410 outputs a signal indicating whether the address of the instruction to be read out is registered or not to a signal line 106. If registered, the corresponding address to be branched is read out to a signal line 105, and if not registered, an adder 412 creates an address for the prefetch of the succeeding instruction word. A forecase checking circuit 420 checks the coincidence of the contents of a register 402 holding the created result of the branch instruction with the contents of a register 418 holding the forecasting information of the branch instruction, and if these contents are inconsistent each other, the table 410 is updated at its contents by a register 423.,下面是Instruction prefetching device forecasting address to be branched专利的具体信息内容。
