Abstract
In another embodiment, an ASIC device includes a first RAM that stores a code for each of multiple first time slots. Each code is combined with corresponding data from a first bus to specify a previously stored operation. A second RAM receives the combined data and code for each first time slot and applies the specified operation for each first time slot to generate modified data for each first time slot. A third RAM stores information specifying a second time slot to correspond to each first time slot and communicates the information for each second time slot as an address. A fourth RAM stores the modified data for a previous frame and the modified data for a current frame, locates the modified data for each first time slot of the previous frame according to the address, and communicates the modified data for each time slot of the previous frame to a second bus in the corresponding second time slot while the modified data for the current frame is being stored.
