SCSI high byte termination case where there is only one 16-bit (wide) device connected to one or more 8-bit (narrow) devices. Then it is possible to wire all the eight spare data bits and the ninth parity bit together and to terminate them with a single resistor circuit to TERMPOWER. So in the case of a differential SCSI bus, it is possible to terminate all 18 spare signal wires with just one resistor. This method is not considered good practice, but has been successfully used in some SCSI products. SCSI high byte termination In SCSI computer systems, there is a special case with mixed
Packed pixel Packed pixel In packed pixel or chunky framebuffer organization, the bits defining each pixel are grouped together. For example, if there are 16 bits per pixel, each pixel is represented in two consecutive (contiguous) 8-bit bytes in the framebuffer (a.k.a. screen buffer). If there are 4 bits per pixel (16 colors), each frame buffer byte defines two pixels, one in each nibble. The latter example is as opposed to storing perhaps half of the bits—2 bits—for each of four pixels in one byte and the other two bits for each of those four pixels in another byte or bytes. It
