Intercommunication of data between adjacent element processors (3) is performed through a memory unit (6) which is independently accessible to the respective element processors (3) without interfere with the operations of the other element processors (3). Thus, memory access and data transfer can be achieved without interfere with the operations of individual element processor (3). Furthermore, it becomes possible to solve differential equations by asynchronous communication system.

A program developing system includes a plurality of graphic editors representing specification definition information a user inputs in representation formats different from each other and a mutual conversion unit for converting specification definition which the user described with a graphic editor into a representation format of another graphic editor. The mutual conversion unit activates another graphic editor to allow input of specification definition by the converted representation format. The graphic editors can hierarchically represent specifications and allows specification description at an arbitrary level. The program developing system includes a parts management unit for registering description of semantically completed specification definition as parts and an execution unit for extracting executable program structure from the specification definition information represented by graphic editors and producing an executable program The executable program reserves the hierarchical structure in the specification description by the user. The execution unit executes a program at an arbitrary level and shows the execution results to the user. By execution and verification of the program at an arbitrary level, the user can know whether a program satisfying the specification is produced or not at a sub program level, which improves the program developing efficiency.

A horizontal synchronizing signal is counted by a binary counter. A first switch is switched in response to the count value, whereby signal data is classified. A sampling clock signal is counted by a binary counter. An output of the first switch is switched by second and third switches in response to the count value, whereby the data input rate of signal data is reduced. Each classified signal is subjected to filtering by a two-dimensional FIR digital filter.

An associative storage comprises two data transmission paths each of which includes a self-running shift register formed in loop fashion. In the respective data transmission paths, data packets each having identification data are transmitted to respective stages of the shift register. The identification data are extracted from the data packets transmitted on the shift registers and compared with each other in a comparing circuit. If and when the identification data of two data packets respectively transmitted on the respective transmission paths are coincident, those two data packets are determined as the data packets to be paired. The data packet pair is read from the data transmission paths.
