Difference Between Microprocessor and Micro-Program in Tabular Form.
| SNO. | Microprocessor | Micro-Program |
| 1. | Microprocessor is an integrated computer circuit on a chip that performs all the functions of a CPU in a computer. | Micro-Program is one of the components of the microprocessor. it is a technique to implement the control logic necessary to execute instructions with in a processor. |
| 2. | The Microprocessor interfaces with the clock, memory and input and output devices. | Micro-Programs are components of all computer CPUs. |
| 3. | The instruction format criterion is fixed. | The instruction format types are variable (16 – 64) bit per instruction. |
| 4. | Fast decoding. | Slow decoding. |
| 5. | Clock rate is 50 – 150 MHZ. | Clock rate is 33 – 50 MHz. |
| 6. | No use of ROM. | ROM is used. |
| 7. | Microprocessors contain a number of micro programs which includes operations like adding, subtracting, comparing two numbers and fetching numbers from one register to another. | Micro-Programs are the components of all computer microprocessors that do not get altered once control units are in operation. |
