A two-pass TMS320C25 for the Motorola EXORMacs

This paper describes the development of a cross-assembler, denoted XTIC25, which runs on Motorola's EXORMacs system. First a suitable data format called TIC25 is derived from the TMS320C25 digital signal microprocessor. This data format is then used in conjunction with software written using a combination of subsets of Pascal and MC68000 assembler routines, based on a two-pass algorithm. The cross-assembler is validated using several test programs and is capable of developing software, using the TMS320C25 assembler, within a microcomputer environment. In this way, the use of a host microcomputer for developing digital signal processing software is demonstrated.
