ABSTRACT:
A method and apparatus for programming hardware registers using a database defining each hardware register and associated bit fields of the registers, input code including bit field write (BFW) commands identifying bit fields corresponding values to program into the bit fields and defining an array of software copies of the hardware registers, and a preprocessor for writing the appropriate code to program the hardware registers. The database provides the name, size and address of each register and the names and sizes of associated bit fields within each register. The preprocessor generates output source code by replacing the BFW commands with code to manipulate software copies of the hardware registers and to write the software copies to the hardware registers. The output source code identifies each of the affected registers and writing appropriate code to access the register only once per BFW command. The database definitions and the BFW commands allow superior organization and simplification to reduce programming time, cost and potential for error.
