The heart of the IBM PS/2 Image Adapter is a VLSI display controller and processor chip utilizing an advanced 1-μm standard-cell CMOS technology. This chip is 9.4 mm square and contains the standard-cell equivalent of 40,000 two-input NAND gates, organized as a matrix of 27,000 wireable cells. It is packaged in a 194-pin IBM pin grid array and consumes approximately 1 W. The display controller and processor chip contains most of the digital logic which gives the Image Adapter its high performance and function. It provides a programmable adapter which can be personalized for image, text, or graphics simply by providing a new microcode load for the on-chip processor. The Image Adapter performs algorithms such as image compression and graphics rotation at rates comparable to hardware, while retaining the flexibility of programmable microcode. A complete set of tools is provided for the processor, including a C language compiler, assembler, linker, simulator, and debugger.
