Title:
DATA TRANSMITTING CIRCUIT
Document Type and Number:
Japanese Patent JP3119275
Kind Code:
B2
Abstract:
PURPOSE: To shorten the time required to transmit sent data, constituted in byte units, with frame constitution in bit units by the transmitting circuit for serial data of frame constitution.
CONSTITUTION: This data transmitting circuit consists of a memory 1 where data in byte units are stored and read out in byte units with a readout signal, holding circuits 2 and 3 which holds the data of the memory 1, a selecting circuit 4 which selects the data of the holding circuit 2 in bit units with a select signal, a counter 5 which inputs frame pulses and a clock and counts the number of bits of frames, and a ROM 6 which outputs the readout signal, holding signals 1 and 2, and select signal as data. Consequently, the frame constitution which is free from a waste of data is provided and a conventional editing process is not required, so the processing time of transmission can be shortened.
