Title:
DATA TRANSFER DEVICE
Document Type and Number:
Japanese Patent JPH0654218
Kind Code:
A
Abstract:
PURPOSE: To decrease the number of signal lines when plural types of data are not transferred at one time.
CONSTITUTION: A black processing unit 100K extracts the 8-bit black data on the value 255 including 0 through 254 out of the RGB data on an original and transfers the bit data BO0-BO7 to a unit 200 via the OR gates 101-107 and the signal lines DT0-DT7. A red processing unit 100R extracts the 1-bit red data OR on 0 or 1 out of the RGB data on the original and transfers the data RO to the unit 200 via the gates 101-107 and the lines DT0-DT7. Then the unit 200 separates the black data from the red data through the gates 201-210 and outputs these data to a black processing unit 200K and a red processing unit 200R respectively.
