COBASS

a component based processor/assembler simulator running on Mac OS X
(current version simulates a sun sparc v8 architecture)

Cobass is a simulation environment for assembly language programming/hardware programming in courses like systems programming. The tool provides access and interactive display of:

• all registers of a SPARC processor.
• all internal state of a SPARC processor.
• memory segments for user/system programm text and data.
• assembler listing with single step display.
• console with character in and out.
• hardware elements like e.g. blinking lights or bus line status.

an integrated GCC compiler permits the direct use of C source code with a fast compile/update cycle

Idee and implementation: Andreas Schweizer, Studiengang Informatik
Term project: "Semesterarbeit" in summer 2001
Rating: Most outstanding performance in software construction (Prof. Thomas M. Stricker)

Download Installation Image of Cobass: cobass.dmg [66MB]
Download Documentation: cobass.docs [2MB]
(the large size is due to the complete version of the gcc cross-compiler for SPARC included)

2. Usage: Use COBASS on one of the five Mac G4 Cubes in IFW D35.
