Computer Systems,Fifth Edition provides a clear,detailed,step-by-step introduction to the central concepts in computer organization,assembly language,and computer architecture. It urges students to explore the many dimensions of computer systems through a top-down approach to levels of abstraction. By examining how the different levels of abstraction relate to one another,the text helps students look at computer systems and their components as a unified concept.
New & Key Features:
New high-order language — The high-order language is changed from C++ to C. The C language is more common as a systems programming language and is more appropriate for a computer systems text.
New sidebars — Each sidebar is a real-world example of the concepts described in that chapter. As most of the chapters describe the Pep/9 virtual machine,the sidebars for those chapters show corresponding implementations for the Intel x86 architecture.
New and expanded topics — New and expanded topics include,QR codes,color displays,Unicode,UTF-32 and UTF-8 encoding,floating point underflow,big-endian and little-endian order,memory alignment issues,and expanded RISC design principles and MIPS coverage to contrast with the Pep/9 CISC design.
New virtual machine — Pep/8,the virtual machine for the two previous editions,is now superseded by the new and improved Pep/9. Pep/9 retains the same eight addressing modes of Pep/8 but now includes memory-mapped I/O,an improved return-from-subroutine instruction,a new native compare-byte instruction,improved instruction mnemonics,and a new hexadecimal output trap instruction.
New software — The Pep/9 system in the text is supported by two updated open source software applications,the assembler/simulator and the CPU simulator.
