What do you mean by instruction set?
An instruction set is a group of commands for a CPU in machine language. The term can refer to all possible instructions for a CPU or a subset of instructions to enhance its performance in certain situations. Some instructions are simple read, write and move commands that direct data to different hardware.
What are types of instruction set?
7 Types of Instruction Set
- Reduced Instruction Set Computer (RISC)
- Complex Instruction Set Computer (CISC)
- Minimal instruction set computers (MISC)
- Very long instruction word (VLIW)
- Explicitly parallel instruction computing (EPIC)
- One instruction set computer (OISC)
- Zero instruction set computer (ZISC)
What makes a good instruction set?
What makes a good ISA? A good ISA should define a set of instructions that can be implemented efficiently in current and future technologies, resulting in cost- effective designs over several generations. A good ISA should provide a clean target for compiled code.
What is instruction set of 8085?
Instruction Set of 8085 An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set. 8085 has 246 instructions. Each instruction is represented by an 8-bit binary value. These 8-bits of binary value is called Op-Code or
