This book contains an overview of assembly language programming and a collection of useful subroutines. The subroutines use a standard format, a documentation package, and parameter passing techniques. Each subroutine is described in terms of purpose, procedure, parameters, results, execution time, and memory usage.

The subroutines emphasize common tasks that occur in many applications, such as, code conversion, array manipulation, arithmetic, bit manipulation, shifting functions, string show more manipulation, sorting, and searching.

There are also examples of I/O subroutines, interrupt service subroutines, and initialization subroutines.

This book is written for engineers, technicians, and programmers who already know assembly language and how to use an assembler. show less
