Abstract

Disclosed is a software implementation of concepts and techniques for testing, analysis (debug), compliance checking, and architecture verification for XGA* video circuits in a personal computer system. The software, which is loaded into the system by means of a diskette, provides the user with a capability to manipulate circuits at a low level, without using the drivers which may be otherwise present in the system, for example, directly manipulating XGA registers and memory.

Software for Exercising and Analyzing XGA Video Circuits

      Disclosed is a software implementation of concepts and
techniques for testing, analysis (debug), compliance checking, and
architecture verification for XGA* video circuits in a personal
computer system.  The software, which is loaded into the system by
means of a diskette, provides the user with a capability to
manipulate circuits at a low level, without using the drivers which
may be otherwise present in the system, for example, directly
manipulating XGA registers and memory.

      The software, which can fully use any hardware of firmware
feature of the IBM XGA architecture, includes support for past and
present levels of this architecture, along with an expandability to
provide support for future levels of this architecture.  Users can
modify code using code libraries supplied with the software.  Key
features of the software include a Video Random Access Memory (VRAM)
editor, an object-oriented subsystem component representation,
individual subsystem component tests and exercises, and built-in
support for all XGA features.

      The Figure shows graphical information which is shown on the
display, providing the user with an ability to select various
features and operations with a mouse.  An image of the video circuits
is also displayed on the screen, providing an object-oriented ability
to choose, for example, the memory, processor, or DMA circuits for
the application of test procedures.
