Abstract: A system and a method are provided for processing Multi-Protocol Encapsulation (MPE) under the DVB-H standard. The system includes: (a) a receive buffer having entries organized as columns and rows and in which the addresses for the entries in the receive buffer are arranged sequentially in column-major order; (b) a first process writing MPE data into the receive buffer, in the manner such that, for each frame, the application data portion and the error correction code portion are written sequentially in column major order, (c) a second process decoding the error correction code portion of each frame and which corrects the application data portion in accordance with the decoding; and (d) a third process reading out the application data portion from the receiver buffer column by column, the third process re-reading any column of the application portion that is corrected by the second process, when that column has previously been read by the third process.

Abstract: A technique to enable accurate timing and functional verification in a negative constraint calculation (NCC) implemented event-driven logic simulators when there are negative constraints in logic elements. In one example embodiment, the technique adjusts negative timing constraints by grouping the timing constraints based on associated output terminals in a digital logic circuit. The NCC is then applied to each grouped constraint to correct for path delays and resulting timing inaccuracy during an event driven simulation.
