Bit addressability
WebSep 13, 2014 · It depends on how you address the data. If you use 32 bits to address each bit, you can address 2 32 bits or 4Gb = 512MB. If you address bytes like most current architectures it will give you 4GB.. But if you address much larger blocks you will need less bits to address 4GB. For example if you address each 512-byte block (2 9 bytes) you … WebApr 10, 2024 · Registers Bit-AddressabilityRegisters Bit-Addressability Only registers ACC (A), B, PSW, IP, IE, SCON, and TCON are bit-addressable While all I/O ports are bit-addressable In PSW register, two bits are set aside for the selection of the register banks Upon RESET, bank 0 is selected We can select any other banks using the bit- …
