Abstract: A processing device includes: a plurality of processing units that perform processes in accordance with data items read from a memory; a bus that connects the memory to the plurality of processing units; and a traffic monitor that monitors traffic on the bus with respect to the plurality of processing units, and when the traffic for one of the processing units that has been assigned access rights to the memory exceeds or reaches a prescribed upper limit, outputs a signal to the one of the processing units so as to reduce or suspend the traffic for the one of the processing units.

Abstract: An electronic musical instrument reads waveform sample data of a predetermined number of channels from memory, corresponding to an empty state of a bus, and, in a case in which reading is not completed before a corruption determination timing of each channel lapses, detects bus corruption, which is overflow of the bus, for channels in which the reading is not completed. Then, in a case in which the bus corruption is detected, the electronic musical instrument performs predetermined control such as not to generate entry data, to stop sound generation, etc. for sound generation in channels in which the reading is not completed.

Abstract: An address for reading, from a waveform memory connected by a bus, waveform data to be assigned to each of a plurality of sound generation channels for generating a musical sound, is calculated, by time division, for each sound generation channel, and the calculated address and the sound generation channels are associated and stored in an address memory. When the bus is in an empty state, an address stored in the address memory is read, and waveform data is read from the waveform memory based on the read address; the read waveform data is assigned to the corresponding sound generation channel, and generation of a musical sound is prescribed for the sound generation channel to which the waveform data is assigned.
