Memory Address Decoding • The processor can usually address a memory space that is much larger than the memory space covered by an individual memory chip. • In order to splice a memory device into the address space of the processor, decoding is necessary. ...
The decoding of these addresses is based on the top 12 bits of the memory base and memory limit registers which correspond to address bits A[31:20] of a memory address. When address decoding, the HOST BRIDGE assumes that address bits A[19:0] of the memory address are zero and that add...
