The real value of Code is in its explanation of technologies that have been obscured for years behind fancy user interfaces and programming environments, which, in the name of rapid application development, insulate the programmer from the machine. In a section on machine language, Petzold dissects the instruction sets of the genre-defining Intel 8080 and Motorola 6800 processors. He walks the reader through the process of performing various operations with each chip, explaining which opcodes poke which values into which registers along the way. Petzold knows that the hidden language of computers exhibits real beauty. In Code, he helps readers appreciate it. --David Wall
Topics covered: Mechanical and electrical representations of words and numbers, number systems, logic gates, performing mathematical operations with logic gates, microprocessors, machine code, memory and programming languages.
Charles Petzold wrote the classic Programming Windows®, which is currently in its fifth edition and one of the best-known and widely used programming books of all time. He was honored in 1994 with the Windows Pioneer Award, presented by Microsoft® founder Bill Gates and Windows Magazine. He has been programming with Windows since first obtaining a beta Windows 1.0 SDK in the spring of 1985, and he wrote the very first magazine article on Windows programming in 1986. Charles is an MVP for Client Application Development and the author of several other books including Code: The Hidden Language of Computer Hardware and Software.
