<p>PURPOSE:To process large-capacity antenna-beam data at a high speed and in a multifunctional manner by making a master processor recognize the number of clusters and equalize a processing load onto every cluster so as to flexibly deal with the number of clusters. CONSTITUTION:A cluster 10 which is constituted of CPUs 1, a local bus 2, a shared memory 3, a high-speed and large-capacity arithmetic network 9 and the like is not specialized to a certain signal processing function, but is performs a flexible arithmetic operation according to the content of a program for the network 9. A master processor(MP) which is constituted of CPUs 1, a bus 2 and a memory 3 and a plurality of clusters 10 are connected in parallel with a system bus 5, the memory 3 for every cluster 10 is allocated on the memory 3 for the MP, and the MP communicates with every cluster 10. Then, every cluster 10 self-diagnoses whether its mounting is effective or invalid in the start or the operation, the MP grasps the number of effectively mounted clusters 10, and the load on every cluster 10 is distributed so as to be processed equally. As a result, large-capacity data can be processed at a high speed.</p> |
