BROADCAST COMMUNICATION TEST SYSTEM

摘要

PROBLEM TO BE SOLVED: To confirm normality, shorten test time and facilitate test equipment of broadcast communication for simultaneously transmitting the same data from one master node to plural slave nodes. SOLUTION: Data is transferred between a master node 1 and plural slave nodes 2 to 2n. The master node 1 is connected with the respective slave nodes 2 to 2n by a HUB 8. The nodes are managed by central processing units 3, 3a, 3n. Transmitted data and received data are stored in main memories 4, 4a, 4n. Transfer of the data, cell conversion and return of the received data are performed by HUB interface control parts 7, 7a, 7n. The transmitted data is transferred to the HUB interface control parts 7, 7a, 7n by DMACs 5, 5a, 5n.
