The document discusses two types of processor architectures: RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer). RISC utilizes a smaller set of simple instructions for efficiency, while CISC supports more complex instructions for multi-step operations but is generally slower. Examples of RISC include ARM and Power Architecture, whereas CISC examples include IBM 370 and Intel 80486.

3. BRIEF TALK ABOUT THE PROCESSOR ARCHITECTURE

4. The term RISC stands for ‘’Reduced Instruction Set Computer’’
This architecture uses a small or reduced set of instructions. Here, every
expected to attain very small jobs.
in this machine, the instruction sets are modest and simple, which help in
more complex commands. These instructions are wound together to get
tasks done in a single operation.
In RISC ,RAM is required to store assembly-level instructions.
In this architecture hardwired control unit is used as a control unit
This architecture include alpha, AVR, ARM, PIC, PA-RISC, and power architecture.

5. The term CISC stands for ‘’Complex Instruction Set
It is a CPU design plan based on single commands, which are
skilled in executing multi-step operations.
It has a huge number of compound instructions, which take
long time to perform. That's why it is little slower in
In this architecture microprogrammed control unit is used as
control unit
Its examples are: IBM 370/168,Intel 80486,VAX 11/780
