Abstract

PURPOSE: To realize an asynchronous reading to the transmission state of data for the data group which is transmitted continuously or intermittently, by connecting the RAM having three memory regions for writing, temporary storage and reading each between the data transmission and reception circuits.
CONSTITUTION: The RAM having three memory regions for writing, temporary storage and reading is connected between the data transmission and reception circuits SEND and RCV. The writing of data into the RAM is performed by converting the asynchronous writing signal WRT produced after preparation of both the transmission address signal AST and the writing data DWRT into the writing signal synchronized with the data writing synchronous signal T3 through the synchronous circuit SINC. On the other hand, the circuit RCV gives the signal to the RAM and then reads the data in synchronization with the data reading synchronous signal T2. Thus the data group transmitted continuously or intermittently can be read asynchronously to the transmission state of data.
