Abstract: A PCMCIA card having an FPGA based card controller that is programmed with FPGA programming data stored on a host computer through a standard PCMCIA bus.

Abstract: Apparatus for storing interlaced video data in a split video memory in noninterlaced form in real video time and without wasted RAM space through the use of a video memory controller that controls transfers between a serial access memory (SAM) including a lower SAM (LSAM) and upper SAM (USAM) and a random access memory (RAM) including a lower RAM (LRAM) and an upper RAM (URAM) of the video memory during free time between video lines when pixel data are not being received, the video memory controller transmitting transfer control signals to the video memory to cause data stored in the LSAM and USAM to be written to the proper page location in the LRAM and URAM after a line has been written in order to save the data before receiving the next line, the controller also generating transfer control signals to cause data in the LRAM and URAM to be read back into the LSAM and the USAM before receiving new data in order to save data that may have already been written into the same page (e.g.
