PROBLEM TO BE SOLVED: To provide performance where the defect of a former design, which is that data is transferred only to one floating point block, is improved by providing plural direct data channels connecting a command preprocessor to plural floating point processors. SOLUTION: A command block 142 interfaces floating point block 152A and 152F through plural buses between two points or direct data channels 154A and 154F. The command block 142 contains the direct channel to the respective floating point blocks 152A and 142F. The direct data channels 154A and 154F collectively contain 48 bits and they are collectively called as CF buses(command/floating buses). Data transfer between the CF buses contains 48 bits transfer executed for six cycles and the start of transfer is synchronized with the different buses. |
