ABSTRACT:
A data processing system2has a base data address region24and a bit-band data address region28. Memory accesses to the bit-band data address region28are converted into memory accesses to the base data address region24. In the process of this conversion specific bits within the base data address region24are picked out for access whether that be via a read-modify-write operation or a masked read operation as appropriate. In this way, bit access is provided to data values within the base data address region24by addressing specific address locations within the bit-band data address region28.
