METHOD OF PRODUCING A DIGITAL SIGNAL PROCESSOR

摘要

In producing digital signal processors generation of behavioral models (18) is used. Such a processor is constituted of hardware modules like computational units and a control unit. The behavioral model (18) is a description of the processor hardware and the program to be executed by the processor, the model being in executable program code written in a HLL programming language. First an architecture of the processor or parts thereof is determined (1) using predetermined templates (17). A layout description of the corresponding circuit is made (21) based on the determined architecture, this layout description being used to produce the layout of the corresponding circuits, so that a semiconductor chip can be processed according to the layout. When making a layout description of a processor part the structure of the processor or part thereof is coded in a textfile (3) as definitions of variables and operations and/or functions which are to be performed using the variables as arguments. These definitions are interpreted (21) to form the respective registers and units performing the functions and lines connecting the registers and the units. The textfile (3) is also used for making the behavioral model (18) that in turn can be used for simulating (18) the processor. A very rapid way of constructing adapted signal processors is obtained hereby, the method being used by a circuit designer interactively with computer software.
