ABSTRACT:
An improved data modem (IDM) and method includes a communication processor module, a mass storage module, a power converter module, and one or more DSP modules. The communication processor module utilizes commercial off-the-shelf components as well as electrically programmable logic devices (EPLD), which are programmed to provide a watchdog timer, programmable interrupt controller, flash page addressing, ISA bus decoder and controller, and various circuits and logic.
