Abstract
A reduced programmable controller for an extensible digital signal processing architecture supports particular instructions to facilitate common digital signal processing operations. These instructions include extract and insert instructions, which are useful in managing the storage and extraction of digital signal processing variables to and from registers, and also useful in assembling fixed-length digital signal parameters from a section of a bitstream stored in a register. These instructions further include leading value detect instructions, including a leading zero detect instruction and a leading one detect instruction which are useful in parsing unique prefix codes such as Huffman codes used in MPEG encoding of video and other variable length codes, and useful in handling of a priority encoder such as a task manager.
