METHOD OF TRANSFERRING AND PROCESSING SERIAL DATA AND DEVICE THEREOF.

摘要

A signal (21) sent from the machine and including a specified signal requiring high speed transfer and high speed processing and ordinary signals other than it is received by a transmission circuit which is common to the specified signal and the ordinary signals and comprises a receiver (22) and a circuit (23) for controlling serial transfer. When an interruption signal (13a) is sent out from a timer (13) for monitoring high speed signals of a numerically controlled equipment (10), serial signals (24) of one cycle, which are transmitted from the circuit (23) to a circuit (11) for controlling transfer in the numerically controlled equipment and are transferred serially from the circuit (11) to a memory (12) by a direct memory system, are processed by a routine high speed signal processing in a processor (14). According to signal processing routine end signal (14a) from the processor, serial signals of the next cycle sent from the transmission circuit are received by the circuit (11), and are transferred to the memory.
