Data transfer apparatus, and method, and semiconductor circuit |
摘要 |
Provided is a data transfer apparatus and method that enables fast data transfer, and has a simple circuit configuration and a small area; and a semiconductor circuit. The data transfer apparatus includes: a data pair generation circuit (301) that transfers a generated data pair during one cycle of a handshake signal communication; a multiplexer (302) that outputs one of the data pair in accordance with a handshake signal; a memory (305) that stores the data output from the multiplexer (302) in response to bi-directional transition of the memory control input signal; a memory control circuit (303) that performs a handshake signal communication and outputs the memory control signal; a request signal waiting circuit (306) that waits until one of the data pair is stored in the memory (305) and the other data is output from the multiplexer (302); and a data pair receiving circuit (307) that receives the data pair in response to a signal from the request signal waiting circuit (306) and outputs the data pair to the transfer destination. |
