Abstract: A system for remotely controlling multiple appliances with a configurable interface for a user. A transceiver device preferably having an infra-red (IR) receiver and transmitters samples and stores IR remote control signals from a remote control device associated with an appliance. The transceiver device communicates with a computer having a user interface program. The user selects an interface and associates an input action with a sampled IR remote signal so that by performing the input action, the computer causes the transceiver device to transmit the sampled signal to the appliance. The system provides the user with a master remote control system capable of controlling multiple appliances from a variable, configurable software interface.

Abstract: A system and method for controlling memory accesses for display data. Pixel data for a display are accessed by a graphics controller having two linear counters, the first counter controlling which column is accessed by the controller, the second counter controlling which row is accessed by the controller. With each successive memory access within a predetermined set of accesses, the first counter increments. When the first counter reaches the end of the row in memory (or another predetermined counting state), the second counter increments. When the second counter increments, the controller necessarily accesses the next row of memory locations.
