Abstract:
An interface that receives display data input from a calculator and outputs video data, comprising:a programmable logic device that receives the display data from the calculator, determines the type of display format used by the calculator, and outputs a format identifier signal indicating the type of display format; and a processor that receives the format identifier signal from the logic device and responds with a control signal to the logic device to determine the processing to be performed by the logic device; memory for storing programming for the processor; wherein the logic device is further operable to perform hard logic processing of the display data and the processor is further operable to receive partially processed display data from the logic device and to perform software processing of the display data, with the division of tasks between hard logic processing and software processing determined at least in part by the type of display format; and wherein the processor is further operable to output video data representing a display on the calculator and having a format suitable for display by a video device.
