EECC250 - Shaaban #1 lec #21 Winter99 ♥ 2-14-2000 Complex Instruction Set Computer (CISC) • Emphasizes doing more with each instruction. Abstract: The author carries out a comparison of CISC (complex instruction set computing) and RISC (reduced instruction set computing). The main intend of the CISC processor architecture is to complete task by using less number of assembly lines. This led to a design called Reduced Instruction Set Computing (RISC), which is now the other major kind of microprocessor architecture. In this, Instructions are … In an 8-bit RISC microcontroller, data is 8-bit wide but the instruction words are more than 8-bit wide (usually 12-, 14-, or 16-bit) and the instructions occupy one word in the program memory. What is the ARM processor? In a CISC processor, a single instruction has ‘several low-level operations’. • Motivated by the high cost of memory and hard disk capacity when original CISC architectures were proposed: – When M6800 was introduced: 16K RAM = $500, 40M hard disk = $ 55, 000 – When MC68000 was introduced: 64K RAM = $200, 10M HD = $5,000 But with the heavy computing demands CISC architecture was becoming more complex and hard to handle. Q1: Compare Complex Instruction Set Computing (CISC) and Reduced Instruction Set Computing (RISC) processor?
