The cpu runs a program's instructions
WebCPU. The central processing unit runs everything. It fetches program instructions over its “instruction side” (IS) bus, reads data over its “data side” (DS) bus, executes the instructions, and writes the results over the DS bus. The CPU can be clocked by SYSCLK at up to 80 MHz, meaning it can execute one instruction every 12.5 ns. The ... WebJun 16, 2024 · Here's a description of the Z80 instruction: The HALT instruction suspends CPU operation until a interrupt or reset is received. While in the halted state, the processor will execute NOP's to maintain memory refresh logic. What use is it to enter a state that can only be exited via an interrupt or reset? Does a NOP loop use less power?
