ABSTRACT:
This is a 32-bit combined arithmetic unit and stack processor (designated as the ASP chip) designed to be a simple, flexible, yet powerful building block for a high level language computer. The ASP is a 3-micron CMOS chip which has run high level programs at 12.5 MHz. When combined with the right hardware and compiler, it will run procedural language programs efficiently. It requires extra hardware to build a complete system, so it is to be mainly where speed is critical; but, employs greatly simplified hardware and software designs. A basic ASP combines arithmetic and stack manipulation functions and is capable of performing 227 different instructions to implement the high level language. A minimum of two ASPs are required to construct a stack-oriented high level language computer.
