<P>PROBLEM TO BE SOLVED: To provide an activation method of a DSP system capable of using a general purpose peripheral device supporting plug-and-play. <P>SOLUTION: An intrinsic data bus 3 to which a plurality of DSPs are connected and a data bus 1 and a data bus 2 are connected by protocol conversion at a bus bridge 11, a master DSP usably sets a plug-and-play peripheral device 14 connected to the data bus 1 by an initialization program loaded from a nonvolatile memory 12 after power is supplied, and issues an activation instruction to a slave DSP, and the slave DSP loads a signal processing program from an external storage device 13 and executes a signal processing program. A host CPU15 connected to the data bus 2 loads the processing program from a data preservation part 17 to the external storage device 13, and transmits an activation command to a DSP card. <P>COPYRIGHT: (C)2012,JPO&INPIT |
