In case you haven t realized it, building computer systems is hard. As the complexity of the system gets greater, the task of building the software gets exponentially harder. As in any profession, we can progress only by learning, both from our mistakes and from our successes. This book represents some of this learning written in a form that I hope will help you to learn these lessons quicker than I did, or to communicate to others more effectively than I did before I boiled these patterns down.

Quality, object.oriented architecture is the product of careful study, decision making, and experimentation. At a minimum, the object.oriented architecture process includes farming of requirements, architecture mining, and hands.on experience. Ideally, object.oriented architecture comprises a set of high.quality design decisions that provide benefits throughout the life cycle of the system.

In today’s IT environment, Java is a leading technology in the world of enterprise development. As management demands more from technology, complexity in infrastructure seems to grow exponentially, leaving many unable to keep up with the demands of such a fast-paced world. These complexities can be seen in the over-evolving Java 2 Enterprise Edition (J2EE) specifications. This unnecessary complexity drove us to discover ways of simplifying development.

This example implements a gameport translator on the PIC16C765. The firmware translates a gaming device plugged into the gameport to a USB gaming device. The firmware is set up to translate the DexxaTM eight-button gamepad. Changes to the firmware will be necessary for a different gaming device.

This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.
