A: Decoding of part of high-order address buses
B: Decoding of the lower order address buses
C: Decoding of all remaining high-order address buses
D: One of the remaining high-order address bus
A: Decoding of part of high-order address buses
B: Decoding of the lower order address buses
C: Decoding of all remaining high-order address buses
D: One of the remaining high-order address bus
举一反三
- which address signals are used to generate the chip select signal of the memory chip for the one-to-one mapping of the memory chip to the logical storage space of the computer system? A: some of the high-order address signals of the address bus B: the lower-order address signals of the address bus C: all remaining high-order address signals of the address bus D: One of the remaining high-order address signals of the address bus
- Which of the following is the correct statement about the one-to-one mapping of storage chips to the logical storage space of the computer system? A: The address of each storage unit of the memory chip is unique but not continuous B: The address of each storage unit of the memory chip is continuous but not unique C: The address of each storage unit of the memory chip is continuous and unique D: The address of each storage unit of the memory chip is neither continuous nor unique
- Computer system IO interface address decoding can use direct decoding method and indirect decoding method.
- The indirect decoding method means that the IO interface addressing requires at least two bus operations. The first bus operation outputs and latches the address through the data bus to the address port in the IO interface. The second bus operation can realize the communication of other ports of the IO interface.
- The width of address bus determines __________. A: word size B: maximum memory capacity of system C: carry data D: control signal
