Digital Signal Processor: Design of the Assembler
C. L. Semmelman · Bell System Technical Journal · 1981
In addition to the features normally provided by assemblers, the digital signal processor assembler handles the multistatement-per-instruction format required by a pipelined machine and provides several other capabilities required by the digital signal processor architecture. In describing the manner in which this was accomplished, more attention is devoted to matters of interest to the user of the assembler and less to its internal construction. The use of “lex ” to write the parser subroutine is described, and possible future enhancements are discussed. An example illustrates the digital signal processor assembler's input language and its outputs.
