Minimizing program code storage for performing regular and repetitive operations in a programmable processor

Process for the simultaneous control of a plurality of execution units of a programmable processor, in which control words destined for different said execution units are generated in succession from a program code stored in a program memory, comprising the steps:

• storing at least a first segment of the program code in a first segment of the program memory in the form of a succession of program words, said succession of program words including a first plurality of first base words and a second plurality of second base words, each first base word corresponding to a respective group of one or more of the control words and each base word having a size less than the sum of the control word of the sizes of the respective group, said second plurality of second base words being fewer in number than said first plurality of the first base words,
• extracting sequentially said program words from said first segment of the program memory,
• providing a common storage facility,
• updating a current content of said common storage facility in response to each extracted second base word to thereby form a respective updated content,
• providing a plurality of elementary storage facilities, each elementary storage facility being assigned to a different one of said execution units, and
• sequentially generating each said group of control words by
• using a first predetermined logical relationship to combine each of the respective extracted first base words with the respective undated contents of the common storage facility to thereby generate a block of first instruction words which are mutually independent, each said first instruction word being assigned to a respective execution unit, and also to thereby generate a plurality of second instruction words each assigned to at least one execution unit,
• updating a respective content of each elementary facility in response to each generated second instruction word that is assigned to that elementary facility, and
• using a second logic relation assigned specifically to each execution unit to combine a respective generated first instruction word that is assigned to that execution unit with a respective content of the respective assigned elementary storage facility.
