摘要:
In a cache memory setup, a buffer register is provided to accommodate the data read from a data memory. Between the buffer register and the data memory is connected a selector. This selector selectively transfers to the buffer register part of the data read from the data memory. The remaining part of the data is replaced with appropriate data for transfer to the buffer register. This arrangement provides the cache memory with a partial-write function.

A plurality of sensor portions detect a variety of physical characteristics of objects to be detected, which are being conveyed on a conveyance passage to asynchronously transmit electric signals indicating results of detection to a processing unit. The processing unit causes an A/D converter to A/D-convert the electric signals transmitted from the sensor portions. A mixer adds, to data, an identifier indicating the sensor portion from which data has been transmitted to sequentially output data for each of the sensor portions. A detection-result processing means receives data output from the mixer to identify the sensor portion from which data has been transmitted in accordance with the identifier contained in received data so as to perform a process for detecting the variety of the physical characteristics. The structure and circuit structure of the transmission passage in the detecting apparatus can be simplified.

A data storage device for storing data strings each including units of data has a plurality of memory sections each for storing therein a table, a plurality of processor elements one provided for each of the tables and a controlling unit having an internal memory in which data strings are stored. The table contains a plurality of records each including a unit of data, a first index data representative of the number of units of data of a data string which the unit of data constitutes and a second index data unique to each individual data string. The processor elements access in parallel their associated tables under control of the control unit for data storage and data retrieval. The first and index data are generated by the controller for the purpose of data storage. For retrieval of data strings: a key data string is divided into units of data; retrieval keys are produced each from a combination of one of the divided units of data and a third index data representing the number of units of data of the key data string; second index data are retrieved in parallel in the tables of the data storage device with the retrieval keys so that a single second index data common to all of the retrieved second index data is found among them; and a data string corresponding to the found common second index data is outputted from the internal memory of the storage device.
