A General-Purpose Cross-Assembler for Producing Absolute Binary Object Code.

摘要

A general-purpose cross-assembler is described. The cross-assembler, written in PL/I, has been implemented on an IBM 370/168 using the time-sharing Conversational Monitor System (CMS). Absolute binary object code will be produced. Although the cross-assembler has been designed with the intention of assembling code for various microprogrammable machines, even code for conventional minicomputers has been assembled. Use of the cross-assembler is discussed assuming a CMS environment. Included are the disk-resident files to facilitate an assembly. Various pseudo-ops, or assembler control statements, are used to describe the machine for which an assembly is done. An example of using the cross-assembler for a parallel microprogrammable digital signal processor (PMP-I) is discussed. (Author)
