More Information
Summary:A multi-mode terminal system utilizes a single embedded processor (14) and a single RAM (12) for performing modem operations, graphics/video processing and general purpose control tasks. The display lists, frame buffer, font area, and embedded processor memory are located in the same single random access memory, thus allowing the use of a single RAM for DSP data, display lists, video buffers, voice compression/decompression algorithms and embedded controller tasks. The system is adaptable for programming the desired video standard, modem type and display list format. Since both the video function and the embedded processor are supported by the same RAM, a RAM arbiter (18) resolves bus contention.
