Types of processor Flashcards
CISC
“Complex Instruction Set Computer”
“A design that produces a complicated and expensive integrated circuit capable of performing a large variety of complex instructions. Complex instructions can be executed with few machine cycles.”
RISC
“Reduced Instruction Set Computer”
“A design that produces a simple, cheap integrated circuit with a basic range of machine instructions. Relies on speed as complex instructions take many machine cycles.”
GPU
“Graphical Processing Unit”
“A specialised electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display. Modern GPUs highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.”
Multicore System
“Development of CISC architecture with several sets of CPU components in one microprocessor.”
Parallel Processor System
“The simultaneous use of several processors to perform a single job. A job may be split into a number of tasks each of which may be processed by any available processor.”
