How would you show the difference between RISC and CISC?
CISC processors reduce the program size and hence lesser number of memory cycles are required to execute the programs….Difference between RISC and CISC processor | Set 2.
| CISC | RISC |
|---|---|
| A large number of instructions are present in the architecture. | Very fewer instructions are present. The number of instructions are generally less than 100. |
What is RISC CISC architecture explain the difference between them?
Difference between RISC and CISC Architecture
| RISC | CISC |
|---|---|
| 4. It has no memory unit and uses separate hardware to implement instructions.. | 4. It has a memory unit to implement complex instructions. |
| 5. It has a hard-wired unit of programming. | 5. It has a microprogramming unit. |
What is the difference between CISC and RISC?
CISC has complex decoding of instruction. Uses of the pipeline are simple in RISC. Uses of the pipeline are difficult in CISC. It uses a limited number of instruction that requires less time to execute the instructions. It uses a large number of instruction that requires more time to execute the instructions.
How many instructions are there in an instruction set in RISC?
RISC instruction sets hold less than 100 instructions and use a fixed instruction format. This method uses a few simple addressing modes that use a register-based instruction. In this compiler development mechanism, LOAD/STORE is the only individual instructions for accessing memory.
What are the characteristics of the RISC processor?
Following are the main characteristics of the RISC processor: The length of the code is shorts, so it requires very little RAM. CISC or complex instructions may take longer than a single clock cycle to execute the code. Less instruction is needed to write an application. It provides easier programming in assembly language.
What are the main characteristics of CISC?
In CISC, instruction pipelining is not easily implemented. The main characteristics of the RISC processor include the following. CISC may take more time to execute the code as compared with an only clock cycle. CISC supports high-level languages for simple compilation and complex data structure.
