Embodiment Construction

[0018] figure 1 Structural features of the present invention are shown. The data processing device according to the present invention comprises a first processor 101, a second processor 102, a third processor 103, a first memory 111, a second memory 112, a third memory 113, a first bus 121, a second bus 122 , the third bus 123 , the first bridge 131 , the second bridge 132 , the third bridge 133 , the first memory table 141 , the second memory table 142 and the third memory table 143 . The three memories 111 , 112 and 113 are combined to form the first memory system 150 . The example shown is for three processors accessing three synchronous dynamic memories. Obviously, the invention can also be used with different numbers of processors or synchronous dynamic memories. The invention can also be applied to other types of memory such as dynamic memory or static memory.

[0019] When the first processor 101 wishes to read or write a data item in the first memory system 150 , i...

Abstract

A data processing device comprises a plurality of processors, for example 101, that are to access a memory system 150. The memory system 150 comprises at least two memories 111 and 112. The data processing device comprises a bus, for example 121, per memory. The buses are interconnected by at least one bridge, for example 131. A processor is connected to a bus, and the data processing device comprises at least one memory table, for example 141, specifying with which memory an exchange of a data item between a processor and the memory system 150 must be effected. The invention allows a reduction of the reaction times in processing the data and an augmentation of the passband. It is notably interesting in systems where the real-time constraint is considerable, for example, in video data processing systems.

Description

technical field [0001] The invention relates to a data processing device using a plurality of processors having access to a memory system. The present invention can be applied in systems dedicated to applications with real-time type constraints such as video data processing equipment like decoders for televisions or receiver decoders (set-top boxes). Background technique [0002] In an integrated circuit, data processing is performed using a plurality of processors capable of accessing data stored in one memory. International patent application WO95 / 32578 describes a decoder for digital television comprising processors and an external memory. Data transfer between the external memory and the different processors is performed via a bus. A control unit controls said external memory and said bus to optimize said data transfer. [0003] Data transfer between a processor and a memory is usually performed via a bus as described in the above-mentioned International Patent Applic...
