The invention relates to a method of graphical entry for the mapping of signal processing applications, intended for a machine comprising passive resources and active resources. It comprises at least the following steps:

Graphic acquisition method for placement of signal processing applications

The invention relates to the methods for automatic placing of the tasks of an application in a signal-processing machine. It consists in determining a Table Distribution Operator (), called TDO, by forming it with a chain of Elementary Operators (), called EOs, which are separated by linking spaces (). These elementary operators are 8 in number, 4 of which are direct and 4 of which are mirrors of the direct ones. It makes it possible to automate the hierarchization in the processing chain of a signal-processing machine operating with the method known by the name of 'ARRAY-OL'.

Automatic application task placement procedure in a signal processing machine

A parallel memory configured to enable access to a table with aligned and equidistant components constituting a vector of N components. The memory ( ) is organized as M memory banks ( ). Each memory bank ( ) includes an address calculator. The memory ( ) also includes a unidirectional network ( ) configured to carry out a permutation of the N components of the vector being accessed and to carry out a translation by a specified value t of the components of the vector.

Method of signal processing application graphical entry

A digital device for forming spatial channels for sonar equipment having a sonar transducer array including N sensors. Signals from the N sensors are sampled and multiplexed in series. A memory having a plurality of memory blocks stores the samples of the sensor signals. The memory blocks may conveniently be divided into two groups. The group acquires samples during a time interval T.sub.c from the N multiplexed signals. Each memory block thus stores P groups of N samples. The samples stored in one memory block are then transferred to the next block. Finally, the samples stored in each memory block of the first group are transferred into the corresponding memory block of the second group in which the delayed samples are read and summed to deliver simultaneously Q time samples of the same spatial channel.

Digital device for the formation of sonar channels

A multiprocessor digital computation system for performing at least one signal-processing chain which includes a number of processes. Each process is executed by means of executing circuits including memories, computing operators and input-output couplers, which are interconnected by means of a bus system. The system includes a sequencer and an address and connection generator, wherein the sequencer includes plural process modules, one for each process to be executed, and indicates at each computing step the state of occupation or non-occupation of the executing circuits and allocates the executing circuits to execute a process to be executed upon availability of the resources necessary for execution of the process.
