US Patent 7549036 Management of access to data from memory

Arbitrary patterns of address locations of digital data can be efficiently read from a memory of a signal processor. For example, a first memory address generator receives a first memory command signal from a first communication register to retrieve a first set of data from memory according to a look up table of memory addresses. The first memory access generator reads the look up table of memory addresses, which contain a second set of memory commands and reroutes the second set of commands to a bypass register. In turn, the second set of memory commands stored at the bypass register are read by a second memory address generator which retrieves a second set of data from memory according to the second set of memory command signals read out of memory by the first memory address generator.
