How do you design an instruction set architecture?
An instruction set architecture (ISA) defines a set of native instructions to be executed directly by hardware. It specifies native data types, instructions, registers, addressing modes, memory architecture, interrupts, and external I/O.
What are the types of instruction set architecture?
Following are the instruction set architectures:
- 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)
What are the factors you need to consider when designing an instruction set architecture?
In designing an instruction set, consideration is given to:
- Instruction length.
- Number of operands.
- Number of addressable registers.
- Memory organization.
- Addressing modes.
What is instruction set and its types?
The instruction set provides commands to the processor, to tell it what it needs to do. The instruction set consists of addressing modes, instructions, native data types, registers, memory architecture, interrupt, and exception handling, and external I/O.
What are instructions in computer architecture?
An instruction is an order given to a computer processor by a computer program. In high-level languages, a language statement generally results (after program compilation) in multiple processor instructions.
What are the two instruction set architecture ISA classifications?
The two main categories of instruction set architectures, CISC (such as Intel’s x86 series) and RISC (such as ARM and MIPS), differ in their instruction complexity and flexibility, but those differences are becoming less defined as technologies are converging.
What are the different types of instructions?
Depending on operation they perform, all instructions are divided in several groups:
- Arithmetic Instructions.
- Branch Instructions.
- Data Transfer Instructions.
- Logic Instructions.
- Bit-oriented Instructions.
What are the three bank types of instruction?
Depending on operation they perform, all instructions are divided in several groups: Arithmetic Instructions. Branch Instructions. Data Transfer Instructions.
What is types of instruction?
Integer Instructions – These include arithmetic, compare, logical, and rotate/shift instructions. Floating-Point Instructions – These include floating-point arithmetic, multiply-add, compare, and move instructions, as well as instructions that affect the Floating-Point Status and Control Register (FPSCR).
How many types of instructions are there?
Data Manipulation Instructions: Data manipulation instructions perform operations on data and provide the computational capabilities for the computer. There are three types of data manipulation instructions: Arithmetic instructions, Logical and bit manipulation instructions, and Shift instructions.
What are the basic types of instructions?
A computer must have the following types of instructions:
- Data transfer instructions.
- Data manipulation instructions.
- Program sequencing and control instructions.
- Input and output instructions.
What are the characteristics of instruction set?
Instruction format: Instruction length (in bits), number of addresses, size of various fields, and so on. Registers: Number of CPU registers that can be referenced by instructions, and their use. Addressing: The mode or modes by which the address of an operand is specified.
