Abstract: Concurrent servicing of a first cable of a cable pair while a second cable of the cable pair remains operational improves multi-processor computer system availability and serviceability. A pair of processing chips in different processing drawers may continue operation by way of the second cable while the first cable is degraded or serviced. Upon the servicing of the first cable, the serviced cable may transition to a fully operational state with no interruptions to the operations between the processing drawers by way of the second cable. Since cable faults are typically more common than processing chip or processing drawer faults, identification of cable faults and the ability to maintain operations of the processing drawers connected therewith is increasingly important.

Abstract: A method for producing images for display by a television receiver wherein each image is in the form of a bitmap. Each of the bit mapped images is resolved into an array of dynamically redefinable characters (DRCs). Each of the DRCs forming the image to be displayed is stored in non-volatile memory. Under the control of the microprocessor, the array of DRCs for each image is copied from the non-volatile memory, into a display RAM, in order to create a bit mapped image and to display each of the bit mapped images in turn.
