Furthermore, as there are many operations in single instruction they use very few registers.Įxamples of CISC are Intel 386, Intel 486, Pentium, Pentium Pro, Pentium II, etc. Besides, we can say that a single instruction has multiple addressing modes. For example loading data from memory, storing data to the memory, performing basic operations, etc. It means that a single instruction can contain many low-level instructions. CISC (Complex Instruction Set Computer)Īs the name suggests, the instructions are in a complex form. We have three basic types of microprocessors. It performs three basic tasks while processing the information. Furthermore, the basic task of a microprocessor is to input the instructions from the memory, decode, and process them and produce the output. It means that all the functions of the processor are included on a single chip. Furthermore, a microprocessor is basically a computer processor that is mounted on a single IC (Integrated Circuit). We can also call it simply a processor or CPU. Let us understand what is a microprocessor.Ī microprocessor is basically the brain of the computer. There are three types of microprocessors namely, CISC, RISC, and EPIC. 6 Frequently Asked Questions (FAQs) Microprocessor
