Types of Microprocessor with Examples
There are numerous different types of microprocessor those are used in the computer and their examples as well.
- RISC
- CISC
- Superscalar Microprocessor
- ASIC
- DSP
- SIMDRI
RISC (Reduced Instruction Set Computer):
RISC means to “Reduced Instruction Set Computer”. Main objective of designing RISC is to decrease execution time that is simplified by the computer’s instructions. RISC has to use just one clock cycle for producing the result on uniform execution time. RISC needs more couples of RAM memory to save all instructions, due to this reason decrease the efficiency for all codes which are used in the lines form.
Examples are:
- SUN’s SPARC and ULTRA SPARC;
- PowerPC processors 601, 604, and more
- MIPS: TS (R10000) RISC Processor
CISC (Reduced Instruction Set Computer):
CISC stands for “Complex Instruction Set Microproce ssors”. CISC has to contain the complex instructions set, and due to that reason CISC take couple to time for executing all instructions, hence its speed slower to RISC. Main goal of CISC is developed for various activities such as download, upload, and swap data between the memory card and other devices which are connected with computer.
Examples are:
- IBM 370/168
- Intel 386, 486, 80486
- Pentium Pro, Pentium, Pentium II, Pentium III, Pentium 4;
- Motorola’s 68000, 68020, 68030, 68040
Superscalar Microprocessors:
Superscalar Microprocessor is able to execute huge tasks at a one time without delay because it has to contain the multiple pipelines structure. Mainly, this microprocessor is designed for the ALU or other types of multipliers as well.
Examples are:
- Pentium, Pentium Pro
- Pentium II, Pentium III
ASIC (Application Specific Integrated Circuit):
Stands for “Application Specific Integrated Circuit”. ASIC microprocessor is not designed for generic purpose because its motive of developing is to specific points such as automotive emissions control or personal digital assistants’ computer.
(DSP) Digital Signal Multiprocessors:
DSP is also known as “Digital Signal Multiprocessors”. DSP processor helps to encode/decode the streaming videos as well as trans form the digital signals to analog signals & analog signals to digital signals.DSP has superb power to calculate the mathematically instructions.
Examples are:
- Texas instruments’ TMS 320C25,
- Motorola 56000,
SIMD Processors:
SIMD (Single Instruction Multiple Data) is also known as “Array processor”. Prime objective of introducing the SIMD processor is to implement all computations into vector form. In SIMD, uses various processing elements in parallel form instead of serially. In that architecture, every processor element has to use couples of ALUs, and every ALU contains their local memory for storing computational data.
