Abstract: This document describes the Micro-SPL language and compiler. The Micro-SPL compiler converts programs in Micro-SPL, a high level programming language similar to C or Algol, directly into microcode for the Xerox Alto minicomputer. The Micro-SPL compiler generates microcode which is competitive with hand microcode, yet takes only 30-50% as long to write and 10% as long to debug. Micro-SPL generated microcode runs over ten times faster than an equivalent BCPL program and perhaps half as fast as good hand written microcode without losing the advantage of writing in a high level language.
