Abstract
PURPOSE: To make data transfer rapid by providing a register where the start part of the signal input at every page switching period is stored and by writing the input signal continuous part in buffer memories and by reading out contents of the register at a buffer memory page switching time.
CONSTITUTION: Register 10 where the start part of the signal input to multiplexer 5 is stored is connected between the first processing unit 1 and multiplexer 6. When one sentence or work code is output from unit 1 due to level change of page switching signal A of signal generating circuit 8, the start part of data written in buffer memories 3 and 4 is stored in register 10 by the control of control circuit 9. Next, after data is written in memories 3 and 4, contents of register 10 are read into the second processing unit 2, and continuously, data stored in memory 3 or 4 is read into unit 2 through multiplexer 6 according to read address C from circuit 9, thus making data transfer rapid.
