Computer system IO interface address decoding can use direct decoding method and indirect decoding method.
举一反三
- 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.
- When the memory chip is mapped to the logical storage space of the computer system using a one-to-many overall mapping method, which of the following solutions can be implemented to generate the chip selection signal of the memory chip? 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
- Companies use two methods to account for uncollectible accounts: the direct write-off method and the allowance method. ( )
- What is the correct processing sequence for acquiring and processing audio signals? A: Quantization, sampling, coding, storage, decoding, D/A conversion B: Sampling, quantization, coding, storage, decoding, D/A conversion C: Quantization, sampling, coding, storage, decoding, A/D conversion D: Sampling, quantization, coding, storage, decoding, A/D conversion
- Decoding determines whether understanding has been achieved during the communication process.
