软件设计者对软件系统运行环境硬件技术是否了解、了解多少会很大程度地影响软件系统的性能,同样,硬件设计者也必须了解他们的设计决策将对软件产生怎样的影响。本书着叟于当前计算机设计中*基本的概念,展示了软硬件间的关系。无论上述的哪一类读者,本书的内容都会使他们对计算机有更深入的认识。
同以往版本一样,本书采用MIPS处理器作为展示计算机硬件技术基本功能的核心。本书逐条指令地列举了完整的MIPS指令集——汇编语言的核心、计算机算术运算、流水线、存储器层次结构以及I/O,并介绍了网络和多处理结构的基本内容。
将CPU性能和程序性能紧密地联系起来是本版的另一个新增内容。作者展示了软硬件部件(如算法、编程语言、编译器、指令集系统结构以及处理器的实现)如何影响程序的性能。另外,本版对软硬件的讨论更加深入,并在光盘中为侧重硬件和侧重软件的读者分别提供了相关资料。
随书光盘的内容非常丰富,不仅包括第9章、附录、本书网站内容、附加习题、术语表、参考文献、索引等,而且还提供了HDL模拟器、MIPS模拟器以及FPGA设计工具等软件。
