Abstract

The Shadow Memory Automation Test Hardware provides the necessary hardware to allow for automated testing of personal computer (PC)-based products. It can transfer screens of data, capture cursor position, and send keystrokes. The tool can be used to automate testing by capturing and interpreting test screens on a PC-based product and responding with the appropriate keystroke(s) to automate the tests.

Shadow Memory Automation Test Hardware

       The Shadow Memory Automation Test Hardware provides the
necessary hardware to allow for automated testing of personal
computer (PC)-based products.  It can transfer screens of data,
capture cursor position, and send keystrokes.  The tool can be used
to automate testing by capturing and interpreting test screens on a
PC-based product and responding with the appropriate keystroke(s) to
automate the tests.

      The Shadow Memory Automated Test Hardware is a two-card set of
PC compatible cards.  The Device Under Test (DUT) card is a totally
passive card to the DUT PC.  It consists of a shadow memory for the
DUT display adapter buffer, shadow cursor latches, and keyboard
control logic.  The driver card interfaces with the DUT card over a
25-pair cable and has a timer, interrupt logic and a keyboard
controller.

      The DUT card is a write-only card from the DUT PC bus. It is
totally passive to the DUT only presenting some bus loading and
requiring power.  It has a 4K-byte dual-port memory.  The DUT side is
a write only shadow of the DUT display adapter buffer.  The Driver
side is read/write and is addressed by a loadable address counter.
The counter is used for automatic incrementing of the address to
support high-speed Direct Memory Access transfers into the Driver PC
memory.  The counter can be pre-set to begin the transfer anywhere in
memory.  It can also be set to increment by 2. This allows for a
transfer of only...
