Hello, readers welcome to the new post. In this post, we will discuss Difference between RISC and CISC. These 2 units are the architectural configurations of the central processing unit according to different commands given. They are categorized based on some points like programming modules. usage, signal, etc.
In the RISC there is the use of hardwiring for programming and in CISC there is the usage of CISC. In this post, we will make differences in 2 units according to different parameters. So let’s get started.
Difference between RISC and CISC
What is RISC
- RISC stands for reduced instruction set computing.
- It is a type of computer that has a small size and high-speed operating group of instructions.
- It uses numerous registers and instruction lines having regular orders and generates a small quantity of CPI.
- Its main function is storing modules where the memory unit gets through certain commands in place of a group of instructions.
- There are numerous categories of RISC such as ARC, Alpha, ARM, etc.
- The ARM structure that is employed in different types of mobiles, tablets such as iPad and Android mobiles belong to the RISC structure.
- It is also employed in supercomputers.
- Most commands in RISC are less complicated and run fastly to work on these commands.
- It used a single clock for the execution of commands.
- Its structure configuration is very basic.
- It uses a small amount to create.
- It needed a smaller number of commands than another system.
- There is no need for an array for this module.
- It does not need any certain codings.
What is CISC
- It stands for complex instruction set computer.
- In this category of computer is there is one unit of commands that can be employed for numerous functions like mathematical functions, and storing of data.
- It also can work at different levels of operations with the use of one instruction.
- An example of this system is mainframe computers.
- Some microcontroller is also part of this system.
- Microcontroller such as 8080, and iAPX432 belongs to this system.
- 6502 and 6809 are part of this system.
- There is a certain category of commands employed in this module that helps to implement commands with high speed.
- It helps to make small-size instructions.
- There is the usage of small numbers of processes to apply different commands.
- It is compatible with to array system.
- It also used conditions coding.
- As comparable RISC it needed a memory unit.
- It is taken as part of a security system used at different levels.
RISC vs CISC
RISC
- The full form is reduced instructions set computer
- It is a microprocessor structure that comes with a small instruction set having a uniform length
- Instructions are applied on a single-clock
- It compatible with a simple addressing format
- It is not compatible with an array
- It is a simple design
- Low-cost modules
- Its basic examples are SPARC and POWER PC.
- It comes with fewer instructions
- It comes with instructions for certain length encoding
- It uses registers for return addresses.
CISC
- Its full form is a Complex Instruction Set Computer.
- It offers many instructions of different sizes.
- it comes with set of certain operation circuits that apply instructions with high speed
- It is compatible with arrays and has larger instructions
- It uses conditions codes.
- It is a complex design and high-cost
- Common examples are Intel architecture, and AMD.
- It comes with higher instructions
- Provides variable-length encodings of instructions.
