Title:
デ―タ処理方法及び入出力装置
Document Type and Number:
Japanese Patent JP2527821
Kind Code:
B2
Abstract:
An input/output device (72) has a processor (202) which processes data strings received by the device (72). When a data string is received, it is passed to a serial interface (207) and a timing means (208). The serial interface (207) generates a signal which interrupts the existing processing by the processor (202) and causes the processor to start processing of the newly received data string. At the same time the timing means measures (208) the length of the data string and compares it with a predetermined length set by user-controllable data setting means (210). If the data string length reaches the predetermined length, the processor (202) is triggered to stop processing the new data string and to recommence the processing it was performing prior to interruption. The unprocessed part of the new data string is stored in a memory (205). In this way, urgent data strings, which are generally short, are processed rapidly and longer data strings are processed after the urgent data strings. It is not necessary for the data string to contain any information to identify its length.
