A register-transfer level (RTL) description of an 8-bit register with detailed implementation, showing how 8 bits of data can be stored by using flip-flops
A processor register is a quickly accessible memory location available to a computer's processor. Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only. In computer architecture, registers are typically addressed by mechanisms other than main memory, but may in some cases be assigned a memory address e.g. DEC PDP-10, ICT 1900.
