Register memory architecture

In computer engineering , a register memory architecture is an instruction set architecture that allows operations to be performed on (or from) memory, as well as registers . [1] If the architecture allows for the use of memory, or in combinations, it is called a “register plus memory” architecture. [1]

In a register memory, one of the operands for ADD operation may be in memory, while the other is in a register. This differs from a load / store architecture (used by RISC designs such as MIPS ) in which both operators for an ADD operation must be in registers before the ADD. [1]

Examples of register memory architecture are IBM System / 360 , ict Successors, and Intel x86 . [1] Examples of register plus memory architecture are VAX and the Motorola 68000 family . [1]
