Abstract: A video picture written in the bit map memory (4) is displayed in a predetermined area on the display screen (70) of the display device (7) within the computer main body (100). The masking memory (2) having a bit number equal to or less than the number of the pixels of the video picture to be inputted is provided separate from the bit map memory (4). When the pixel data of the video picture data has been inputted, the input pixel data is selectively written in the bit map memory (4) based on the contents of the masking memory (2). In displaying a compressed picture of the input video picture on the display screen, an oblique line generating algorithm is used.

Abstract: A housing and cooling structure for a personal processor module (PPM) is provided which includes a case which is sealed and will fit within both a desktop sized docking station and a smaller notebook sized docking station. Within the case, the components which make up the PPM are located in such a way as to minimize the size of the printed circuit boards. In addition, a cooling mechanism is provided which cools all of the components within the case. Also, the PPM has structure for converting 3.3 volt signals into 5 volt signals and for permitting easy upgrades.
