This book describes and compares the architectures and characteristics of today's advanced PC and workstation microprocessors: Intel's 80386, Motorola's 68030, DEC's MIPS chip, etc. It features the latest "RISC" (Reduces Instruction Set Computer) chips - Intel's recently announced i860 and Motorola's 88000 - and contrasts the benefits and drawbacks of these chips compared to the older "CISC" (Complex Instruction Set) designs. It is the first book to provide information on IBM's new RISC chip and Intel's i860.
