A programmable logic device is provided that includes at least one dedicated output routing channel configured to facilitate the processing of output signals generated by multiple function-specific blocks. Also an impact modifier which is preferably of a shell-core structure prepared by the emulsion polymerization process and has a pH of about 3 to about 8. Vent structures including channels, holes, slots, and so forth are designed to provide pathways for gas released by feature elements to escape. The processor may further include a third pipeline stage configured to store the disparity values and the outbound message in a memory, wherein the outbound message is used by the second pipeline stage as one of the inbound messages during processing of a second tile selected from the first image.
