Abstract
A serial data transfer apparatus includes a decoder, a counter, and a calculation circuit. The decoder is configured to decode serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data. The counter is configured to count a frame synchronization pulse. The calculation circuit is configured to generate a chip select signal based on the transfer type information and the base address, as decoded by the decoder, and a count value of the frame synchronization pulse output by the counter.
Claims20
A serial data transfer apparatus, comprising:
- a decoder configured to decode serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data;
- a counter configured to count a frame synchronization pulse;
- and
- a calculation circuit configured to generate a chip select signal based on the transfer type information and the base address, as decoded by the decoder, and a count value of the frame synchronization pulse output by the counter.
A serial data transfer method, comprising:
- causing a decoder to decode serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data;
- causing a counter to count a frame synchronization pulse;
- and
- causing a calculation circuit to generate a chip select signal based on the transfer type information and the base address, as decoded by the decoder, and a count value of the frame synchronization pulse as output by the counter.
An image formation apparatus, comprising:
- an engine configured to read image data of an original document;
- and
- a serial data transfer apparatus configured to write the image data in a storage unit,
- wherein the serial data transfer apparatus includes:
- a decoder configured to decode serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data,
- a counter configured to count a frame synchronization pulse, and
- a calculation circuit configured to generate a chip select signal based on the transfer type information and the base address, as decoded by the decoder, and a count value of the frame synchronization pulse as output by the counter.
A non-transitory computer readable recording medium that stores a program for causing a computer to perform a method comprising:
- decoding serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data;
- counting a frame synchronization pulse;
- and
- generating a chip select signal based on the transfer type information and the base address, and a count value of the frame synchronization pulse.
