A method and apparatus for a fully programmable and configurable application specific integrated circuit (FPCA). Programmable I/O cells are programmed for selected electrical characteristics, including power and ground. The circuit contains a functional core for programming the circuit, programmable I/O leads to connect to the programmable I/O cells, and programming logic and control for programming the functional core and I/O cells. Certain leads double as programmable I/O leads and programming control leads, and are used to communicate with the programming logic and control and the I/O cells. A method of programming the FPCA comprises the steps of asserting the programming control signal; applying programming voltage and ground to a respective two designated I/O cells' leads; isolating a plurality of the I/O cells from the programming signal; and programming an FPGA array in addition to the isolated I/O cells of the circuit.

Fully programmable and configurable application specific integrated circuit

A memory interface controller apparatus for use in a digital system, such as a graphics display system. The apparatus comprises apparatus for receiving incoming pixel data and apparatus for detecting pixel address collision. In an alternate embodiment, apparatus for performing hidden surface removal on the incoming pixel data is included. The memory interface controller apparatus further may include apparatus for construction of images with transparent objects.
