Data Center Insider Article: What Is RISC? And What Is CISC?

By July 8, 2019May 12th, 2021No Comments

RISC stands for Reduced Instruction Set Computer and describes a new working concept for CPUs . It was developed in Stanford in the late 70s and early 80s.
Computers worked until the invention of RISC according to the CISP (Complex Instruction Set Computer) principle. To understand RISC, it makes sense to first take a look at CISC.
The CISC concept aimed to translate a command into as few as possible assembly lines. In addition, a CISC instruction should as little as possible require further instructions, such as register calls, to execute it. Therefore, many complex commands have been implemented directly in hardware. RISC, on the other hand, relies on very simple commands that are to be implemented within one clock cycle. This creates more lines of code, but each command expires faster.
