Study summary of the week four

The processor execution instructions encode the instruction as a binary

Instruction Conversion Mode:

Determining the length of the instruction, dividing the sequence

determine specific directives;

Register designator byte determines register, determines address and other information

The logic gate is the computing element of the computer, and the composing circuit is calculated

Each instruction requires several bytes, and the first byte of each instruction indicates the type of instruction: High 4 bits is the code part, low 4 bits is the functional part

Sequential implementation of Y86
Fetch instruction from memory, extract instruction code from instruction, remove register byte, take out register operand indicator
Decoding reads the operand from the register and gets the value
Execution: Alu either performs the operation specified by the instruction
Write Data to Memory
Write a meeting file
Update

The program counter will use the new command address after the replacement cycle
