Application Description

TOM Computer Simulator For Computer Architecture and Programming Courses. TOM allows interactive programming that includes branching, looping, subroutine calls with stack operations, input and output operations, interrupt processing and memory mapped output. Any TOM program can be seen executing on the main screen or by TOM's underlying machine. A collection of interactive screens show how the elements of TOM are built from logic gates. TOM's comprehensive multimedia presentation gives background information on: Number systems. ASCII collating sequence, Binary encoded decimal. Logic gates. Stacks and subroutines. Numeric overflow.

TOM has 20 instructions, a manageably small number which nevertheless enables real programs to be written. The entire status of TOM is visible at all times giving instant feedback on the state of the execution. Programs may be executed, single stepped, saved, restored, and modified.

The main TOM screen, shown above, behaves exactly as with version 1 but additional options allow programming of memory mapped output and interrupts for the more advanced aspects of current computing courses. In addition, Stack Pointer and Status registers can be enabled to allow a greater range of programs to be written.

The above screen shot shows the optional keyboard device which can provoke processor interrupts for which the students can provide interrupt handlers. Also shown is the memory mapped output device which maps the ASCII collating sequence to displayable characters.

All programs written for TOM can be executed by TOM's machine, as shown on the previous page, where each aspect of execution can be seen in detail.

Logic gates are the fundamental building bricks of digital computers. No student can completely understand the modern digital computer without a firm grasp of what logic gates do and how they can be connected to achieve complex logic circuits.
