A processing apparatus includes a network of interconnected processors comprising a plurality of signal processors for digitally processing input signals in real time to generate output signals and one or more control processors, each control processor controlling the operation of a plurality of signal processors. The processing apparatus automatically schedules control tasks in a plurality of time slices, where more than one control processor is provided for coordination between control processors, a wired-OR configuration connection can be provided to synchronise the beginning and/or end of the time slices. A control processor can change an address field of microcode instructions of a signal processor for implementing a multiplexer function. A control delay list can be provided for scheduling control task delays. Control tasks can be allocated to more than one control processor, each control processor then communicating to the other control processors if it completes the task so that the other control processors may abandon further processing of the task. The invention finds particular application to an audio mixing console.

Signal processing apparatus

This invention relates to the allocation of object code in multi-processor systems. In particular, techniques are disclosed for efficiently allocating signal processing instructions to a large array of parallel signal processing units.

Data storage apparatus comprises: a memory having a plurality of addressable memory locations for storage of data items and memory address input means for receiving addresses of locations to be accessed; main input means for receiving an input address corresponding to a memory location; a counter for changing a count in response to a clock signal; address adjustment means for combining the count with an input address to generate an adjusted address corresponding to a memory location and supplying the adjusted address to the memory address input means; and means for accessing the memory location at the address supplied to the memory address input means. Also provided is a data storage method, and data processing systems including the data storage systems.
