MEMORY ACCESS CONTROL DEVICE AND PRODUCTION METHOD

摘要

This memory access control device is provided with: a bit position information storage unit for storing bit position information indicating one or more bit positions in a bit string having a predetermined length; a readout unit which makes an attempt to read out a bit string having a larger number of bits than the number of bits in the range of a storage area designated by a logical address from a memory in units of the predetermined length; and a bit string extraction unit for extracting bits at the bit positions indicated by the bit position information stored in the bit position information storage unit in units of the predetermined length from the bit string taken out of the memory by the attempted readout by the readout unit.
