  9. What is Computer Architecture?Easy Answer Computer Architecture = Instruction Set Architecture + Machine Organization

  10. The Instruction Set: a Critical Interface software instruction set hardware

  11. Instruction Set Architecture • A very important abstraction: • interface between hardware and low-level software • standardizes instructions, machine language bit patterns, etc. • advantage: allowsdifferent implementations of the same architecture • disadvantage: sometimes prevents adding new innovations • Modern instruction set architectures: • 80x86/Pentium/K6, PowerPC, DEC Alpha, MIPS, SPARC, HP

  12. What is Computer Architecture?Better (More Detailed) Answer Application Operating System Compiler Firmware Instruction Set Architecture Instars. Set Proc. I/O system Datapath & Control Digital Design Circuit Design Layout

  14. Computer Architecture

  15. Features and benefits • Intel® Core™2 Duo processor • With an you will get performance-rich technologies, including up to 6MB of shared L2 cache, up to 1333 MHz Front Side Bus, plus these additional Intel® technologies built in: • Intel® multi-core processing • Provides greater multitasking performance by combining two independent processor cores in one physical package¹ • Intel® Wide Dynamic Execution • Improves execution time and energy efficiency with more instructions per clock cycle • Intel® Intelligent Power Capability • Enables smarter, more energy-efficient performance • Intel® Smart Memory Access • Improves system performance by optimizing the use of the available data bandwidth • Intel® Advanced Smart Cache • Enables higher performance and more efficient cache subsystem by optimizing for multi-core processors • Intel® Advanced Digital Media Boost accelerates • A broad range of applications including video, speech and image, photo processing, encryption, financial, engineering, and scientific applications Computer Architecture
