An apparatus and a method for playing back selectively a desired part of continuous data by using an input event as a clue. The apparatus comprises: first storage means for storing continuous data sequentially inputted; second storage means for storing a plurality of input events occurring at arbitrary times during the continuous data sequence; third storage means for storing data enabling identity of addresses a in the first storage means of locations in the continuous data sequence respectively corresponding to the input events; specifying means for specifying one of the input events stored in the second storage means; and playback means for playing back a selected portion of the continuous data stored in the first storage means in accordance with the identifying data stored in the third storage means which corresponds to the input event specified through the specifying means.

A data retrieval system capable of carrying out the retrieval using the secondary information of the primary data to be retrieved such as environmental information or structural information as the retrieval key. In the system, the primary data which are filing target to be stored and retrieved are stored in a first memory while secondary information associated with the primary data, which are not directly related with data content of the primary data, are stored in a second memory in correspondence to the primary data stored in the first memory. Then, when a retrieval key specifying a desired retrieval of the primary data from the first memory is entered, the secondary information is selected from the second memory in accordance with the retrieval key, and the primary data corresponding to the secondary information selected in accordance with the retrieval key is retrieved and outputted as a retrieval result.

Data retrieval system using secondary information of primary data to be

A method and an apparatus for multi-window display with enhanced window manipulation facilities. In the apparatus, window images to be displayed in multi-window display are stored in a bit map memory. Various image processing operations are performed on the window images stored in the bit map memory, by regarding the window images as graphic images. Appropriate sections of processed window images are transferred to a frame buffer by using a bit block transfer device, and the image in the frame buffer is displayed on a display device.

A parallel-accessible memory device of one or multiple dimensions has submemories for the respective dimensions. Each of the submemories has a capacity provided by dividing the total memory capacity by positive integers given for the respective dimensions. The memory device comprises an address converting section for generating addresses of the submemories of the respective dimensions according to dimensional addresses; a data rearranging section for rearranging input and output data of the submemories in a required order, the input and output data being specified by the submemory addresses from the address converting section; and a write controlling section for selectively renewing data in a region of the submemories of the respective dimensions.
