What is the data path of a processor?

A data path (also written as datapath) is a set of functional units that carry out data processing operations. Datapaths, with a control unit, make up the CPU (central processing unit) of a computer system. A larger data path can also be created by joining more than one together using multiplexers.

What are the four basic types of operations that need to be supported by an instruction set?

Instruction types

• Data handling and memory operations.
• Arithmetic and logic operations.
• Control flow operations.
• Coprocessor instructions.
• Number of operands.

What is data path size?

A datapath is a collection of functional units such as arithmetic logic units or multipliers that perform data processing operations, registers, and buses. A larger datapath can be made by joining more than one datapaths using multiplexers.

What is the ideal CPI of a pipelined processor?

1
The pipelined processor ideally would have a CPI of 1, because a new instruction is issued every cycle.

What are the big buses called?

omnibuses
It is larger than a car. The name is a shortened version of omnibus, which means “for everyone” in Latin. Buses used to be called omnibuses, but people now simply call them “buses”.

What are the three basic types of instruction?

Arithmetic, logical and shift instructions.

What is 32 bit instruction set?

A program written in machine language is a series of 32-bit numbers representing the instructions. Like other binary numbers, these instructions can be stored in memory. This is called the stored program concept, and it is a key reason why computers are so powerful.

How does a data path work?

A datapath is a collection of functional units such as arithmetic logic units or multipliers that perform data processing operations, registers, and buses. A data path is the ALU, the set of registers, and the CPU’s internal bus(es) that allow data to flow between them. …
