It has proven much easier to design pipelined CPUs if the only addressing modes available are simple ones. Most RISC architectures have only about five simple addressing modes, while CISC architectures such as the DEC VAX have over a dozen addressing modes, some of which are quite complicated. Visa mer Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how the Visa mer Some instruction set architectures, such as Intel x86 and IBM/360 and its successors, have a load effective address instruction. This calculates the effective operand address and loads it into a register, without accessing the memory it refers to. This can be … Visa mer Sequential execution The CPU, after executing a sequential instruction, immediately executes the following instruction. Visa mer There are no generally accepted names for addressing modes: different authors and computer manufacturers may give different names to … Visa mer Computer architectures vary greatly as to the number of addressing modes they provide in hardware.
