This the third edition of the Writing Device Drivers articles. The first article helped to simply get you acquainted with device drivers and a simple framework for developing a device driver for NT. The second tutorial attempted to show to use IOCTLs and Display what the memory layout of Windows NT is. In this edition, we will go into the idea of contexts and pools. The driver we write today will also be a little more interesting as it will allow two user mode applications to communicate with each other in a simple manner. We will call this the “poor man’s pipes” implementation.

This document is an operation guide for the MPC8XXFADS board. It contains operational, functional and general information about the FADS. The MPC8XXFADS is meant to serve as a platform for s/ w and h/w development around the MPC8XX family processors. Using its on-board resources and its associated debugger, a developer is able to download his code, run it, set breakpoints, Display memory and registers and connect his own proprietary h/w via the expansion connectors, to be incorporated to a desired system with the MPC8XX processor.

DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the Display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.
