Abstract
The invention relates to a multitask processing system including a data bus and a command bus. Each one of a plurality of operators is provided to perform a processing determined by an instruction and is likely to issue a command request in order to receive an instruction from the command bus and to issue a transfer request on response to an acknowledgment of the command request, in order to receive or provide data being processed, through the data bus. A memory controller arbitrates the transfer requests and manages the data transfers on the data bus between the operators and a memory. A sequencer arbitrates the command requests, determines instructions to provide the operators with, and manages the instruction transfer through the command bus.
