Abstract
In a data processing device connectable to a bus, a plurality of function parts can be operated at the same time so that data transfer between buses or within the device can be efficiently performed. Each of the function parts provides a different function with respect to a signal input through the bus. A plurality of state-machine parts are connected to the respective function units. Each of the state-machine parts is operable independently.
Claims5
A data processing device adapted to be connected to a first bus, said data processing device comprising:
- a plurality of function parts each of which provides a different function with respect to a signal input through the first bus;
- and
- a plurality of state-machine parts connected to a respective one of the function parts, each of said state-machine parts being operable independently,
- wherein each state-machine part detects whether an instruction provided on the first bus is provided for the respective function part to which it is connected.
