For Assembly Language and Architecture courses emphasizing SPARC architecture found in computer science, engineering and business departments. Written from a programmer's perspective, this long-awaited revision introduces the SPARC assembly language to readers early on. Other introductory material encompasses making use of UNIX tools (the m4 macro processor; the assembler; the gnu emacs editor; and the gdb debugger). Further coverage includes a formal definition of the von Neumann machine, its relationship to programmable calculators, and to the JAVA bytecode and JAVA virtual machine. Not only is this book suitable for introductory computer architecture courses, but for programmers who will be programming SPARC architecture machine in languages such as C and C++.
