A Users Manual for a PDP-11 Cross Assembler (CRASS) for the TI-9900 Microprocessor.

Abstract

This report describes CRASS, a two-pass cross-assembler for the TI-9900 microprocessor. The assembler was written in GIRL-FORTRAN to be used on a PDP-11 computer with an RT-11 operating system. It uses the standard TI9900 mnemonics and allows for most of the same assembly time directives. CRASS has the following features: Symbolic memory addressing. Portability - Since CRASS is written mostly in FORTRAN, it can be easily adapted to any machine having a FORTRAN IV compiler, Left to right arithmetic expression handling in binary, decimal, or hexadecimal, Logical expression handling, Specified program starting address; however, there is a default value, and Less program assembly time than with the TI assembler since the code which is created is non-relocatable and therefore does not require a linkage step.
