Abstract: Presented herein are system(s), method(s), and apparatus for reducing on-chip memory requirements for audio decoding. In one embodiment, there is presented a method for decoding encoded audio signals. The method comprises fetching a first one or more tables from an off-chip memory; loading the first one or more tables to an on-chip memory; applying a first function to the encoded audio signals using the first one or more tables; fetching a second one or more tables from an off-chip memory after applying the first function; loading the second one or more tables to an on-chip memory; and applying a second function to the encoded audio signals, using the second one or more tables.

Abstract: A system and method for displaying frames with dynamically changing display parameters is described herein. The display engine stores new display parameters detected by the decoder in one buffer of a ping pong buffer, while continuing to use another set of display parameters stored in the other ping pong buffer. The display engine switches the buffers when the first frame for which the new display parameters are applicable is to be presented.

Abstract: Present herein is a low memory and MIPS efficient technique for decoding Huffman codes using multi-stage, multi-bits lookup at different levels. A binary tree is cut at levels depending on the quotient of the number of existing nodes and the number of possible nodes.

Abstract: Presented herein is a system and method for reducing the total size of the frame buffer portion of a decoding circuit. The reduction in size is possible because first portions of B-pictures are displayed while second portions occurring later in the raster order are decoded. The foregoing allows the second portions occurring later in the raster order to overwrite third portions of the picture that have already been displayed. As a result, the frame buffer for providing the frame from a decoder to the display engine need only store the portion that is being displayed and the portion that is being decoded.

Abstract: Disclosed herein are system(s), method(s), and apparatus for simultaneously displaying multiple video streams. The video streams are encoded as a video sequence, which can include temporally coded bi-directional pictures. A decoder decodes a picture from each of the video sequences, which can include temporally coded bi-directional pictures. The set of frame buffers stores the past prediction frames and the future prediction frames for each video sequence. A table indicates the location of the past prediction frame and the future prediction frame for each video sequence. A display engine prepares a frame from each video sequence for display. The location of the frames for display are indicated by a register.
