Abstract
A data processing systemhas a base data address regionand a bit-band data address region. Memory accesses to the bit-band data address regionare converted into memory accesses to the base data address region. In the process of this conversion specific bits within the base data address regionare 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 regionby addressing specific address locations within the bit-band data address region
