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...
The Altair 8800 is a computer kit based on the Intel 8080 CPU, designed by Micro Instrumentation and Telemetry Systems (MITS), which was headed by H. Edward Roberts, in 1974. It became the first-ever commercially successful personal computer, especially compared to the first microprocessor-based...
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 and pushes the 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 If the ox shall push a manservant...

1994's big risk is the introduction of the Power PC which, unless you're new to the Mac or you've just returned from a lengthy sabbatical, you'll know is a Reduced Instruction Set Computing (RISC) microprocessor that Apple intend to use in a new range of Macs to be launched this Spr...
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 ...
