tailieunhanh - Computer Organization and Design, Fourth Edition: The Hardware/Software Interface

We believe that learning in computer science and engineering should reflect the current state of the field, as well as introduce the principles that are shaping computing. We also feel that readers in every specialty of computing need to appreciate the organizational paradigms that determine the capabilities, performance, and, ultimately, the success of computer systems. | REVISED PRINTING COMPUTER Organization kAND Design THE HARDWARE SOFTWARE INTERFACE M-OICAN KAU MAMM MIPS Reference Data Card Green Card 1.
