Instruction Register (IR) 指令寄存器 The purpose of the Instruction Register (IR) is to shift in instructions via the TDI signal. Additionally, the instruction register can hold the current instruction until the new instruction is completely shifted in. Generally, an IR consists of two registers as shown in Figure 1. The Hold register stores the previous … Read more

In the early stages of IC design, the main parameters of concern were performance (timing) and area. EDA tools minimized area while meeting performance requirements. At this time, power consumption was not a major concern. Because CMOS technology exhibits relatively low power consumption at lower clock frequencies, leakage current can be negligible. However, as transistor … Read more
