    • In a digital signal processor for pipeline processing divided into at least three steps, i.e., instruction fetch cycle, instruction decode cycle and instruction execution cycle, a value of a register (A) is put on a data bus assuming the condition is consistent when a condition execution instruction is decoded in an instruction decoder (14). Then, in the instruction execution cycle of the condition execution instruction, a register (B) introduced the value on the data bus when upon consistency of the condition. As a result, even before a condition flag (Z) changes as a result of execution of the instruction for generating the condition in the instruction execution cycle, the condition execution instruction can be decoded. Thus, the processor may omit an instruction other than “condition generation instruction or condition execution instruction” which was conventionally required.
    • 在用于流水线处理的数字信号处理器中,分为至少三个步骤,即指令提取周期,指令解码周期和指令执行周期,寄存器(A)的值放在数据总线上,假设条件是一致的,当a 条件执行指令在指令解码器(14)中解码。 然后,在条件执行指令的指令执行周期中,当条件一致时,寄存器(B)将该值引入数据总线上。 结果,即使在条件标志(Z)作为执行用于在指令执行周期中生成条件的指令的结果而变化的情况下,可以对条件执行指令进行解码。 因此,处理器可以省略除常规要求的“条件生成指令或条件执行指令”之外的指令。
