Abstract

The present invention is directed to a hardware device for parallel processing a determined instruction of a set of programmable instructions having a same format with an operand field defining the execution steps of the instruction corresponding to the execution of micro-instructions, comprising decision blocks (12—20) being each associated with a specific instruction of the set of programmable instructions, only one decision block being selected by the determined instruction in order to define which are the specific micro-instructions to be processed for executing the determined instruction, activation blocks (22-30) respectively associated with the decision blocks for running one or several specific micro-instructions, only the activation block associated with said selected decision block being activated to run the specific micro-instructions, and a micro-instruction selection block (46) connected to each activation block for selecting the specific micro-instructions to be executed.
