Abstract
As microprocessor-based systems become gradually larger, the developers need good tools for debugging the hardware and software. The emulators for the IBM Personal Computer using an RS-232 serial port are available in the market. But it takes quite a long time to download the user file to the memory of the emulator or the target system. This emulator is an add-on card dedicated for IBM Personal Computers. The emulator communicates with the IBM Personal Computer through the I/O channels on the mother board instead of the serial port, so its speed is much faster than that of the serial port. The debugging software is menu-driven. To display characters on the screen, the characters are written on the display RAM directly instead of calling the ROM-BIOS subroutines. This speeds up the execution of the software.
The illegal memory access is detected through the 64 x 9 bipolar RAM, 82S09, programmed by the command file.
