Describe hardwired control unit in detail
WebHardwired control: To execute instructions, a computer's processor must generate the control signals used to perform the processor's actions in the proper sequence. This sequence of actions can either be executed by another processor's software (for example in software emulation or simulation of a processor) or in hardware. Hardware methods fall … WebJul 24, 2024 · A hardwired control is a mechanism of producing control signals using Finite State Machines (FSM) appropriately. It is designed as a sequential logic circuit. The final circuit is constructed by physically connecting the components such as gates, flip …
