ABSTRACT:
A wireless communications device (110) has a digital section (800) and a radio frequency section (840). The digital section (800) does setup and execution on a set of data in at least first and second threads concurrently in a series of overlapping iterations by dividing the set of data into at least two different subsets and concurrently reading and writing in both subsets. A state machine (1010, 1100) is shared by the setup and execution iterations. Two or more memory units (930, 940) segregate the set of data, the predetermined size of the set of data in the memories (930, 940) combined comprehending the total number of addresses occupied by the set of data utilized in operation of circuitry (910). Dirty bits (1430) are accessible at addresses corresponding to addresses in the memory. A selector circuit (1412) has a selector output selectively coupled to an address line, and to a data line. The selector circuit (1412) responds to a state on a dirty bit line (db) to couple data bits related to the address bits themselves from the address line (1421) to the selector output (1412). Other circuits and methods of manufacture and operation are also disclosed.
