Abstract
A computer program that is embodied on a storage medium for execution on a processor is provided. With this computer program, A current cost is calculated for each transition on a bus having a predetermined width for a functional circuit so as to form a transition cost matrix. Then, a predetermined number of the lowest cost transitions for from the transition cost matrix is determined so as to generate a probability transition matrix. The product of the probability transition matrix and the transition cost matrix can be iteratively determined, while also updating the probability transition matrix until the probability transition matrix converges.
Claims5
An apparatus comprising:
- a functional circuit;
- and
- a codec that is coupled to the functional circuit, wherein the codec includes:
- a buffer that is configured to receive transmission data from the functional circuit and to provide reception data to the functional circuit;
- a lookup table (LUT) having a probability transition matrix for encoding and decoding, wherein the probability transition matrix is a transition pattern encoded matrix based on a transition cost matrix corresponding to an average current cost for the functional circuit that is substantially minimized over a plurality of transitions;
- and
- a controller that is coupled to the buffer, that is to configured to encode the transmission data using the LUT to generate encoded transmission data, and that is configured to decode encoded reception data using the LUT.
