in an instruction set, an opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed. it's like the verb in a sentence. on the other hand, an operand is the part of the instruction that specifies the data on which the operation ...
An ISA that has been widely implemented is Microprocessor without Interlocked Pipelined Stages (MIPS), which is based on thereduced instruction set computer(RISC) architecture. All MIPS instructions are 32 bits long, with the operand specified in the first six bits. MIPS supports three types of i...
In most computers, individual instructions are stored as machine code with each instruction being given a unique number (its operation code or opcode for short). The command to add two numbers together would have one opcode, the command to multiply them would have a different opcode and so on...
When the microprocessor decodes the JSR opcode, it stores the operand into the TEMP register andpushesthe current contents of the PC ($00 0128) onto the stack. (obsolete) To thrust the points of the horns against; to gore. * Bible, Exodus xxi. 32 ...

A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode(four bus clock cycles), fetch operand address Suppose a computer using direct mapped cache has ...
0, 1 — opcode 2, 3 — source 1 4, 5 — source 2 6, 7 — destination Now, what exactly is assembly language? It's as close to machine code as you can get when programming a microprocessor. It is human-readable code based on the machine's supported instruction set and not just ...
- Till an instruction is completed the signal of INTR will remain high. Once an instruction is completed the processor sends an acknowledgement signal INTA. - As soon as the INTA signal goes low a new opcode is placed on the data bus for transfer. ...
An ISA is what determines what operations a microprocessor can do. It is basically a list of instructions tagged by an operation code (opcode) stored in memory. When the processor calls for a specific opcode, it executes the instruction the opcode represents. Common instruction within the ISA i...
