Claims46
(canceled)
A multiprocessor system comprising:
- a plurality of data processing units, each of the data processing units:
- (a) being programmable;
- and
- (b) being adaptable for sequentially processing data in a clocked manner;
- and including
- (c1) at least one Arithmetic Logic Unit (ALU) and
- (c2) at least one data register set, for storing intermediate results in sequential data processing
- at least one bus system for at least interconnecting at least some of the data processing units, each being provided a supply voltage by a voltage supply;
- wherein for at least some of the data processing units, the clock frequency is adjustable at runtime without affecting the clock frequency of at least one of:
- one other of the data processing units and the bus system;
- and
- wherein the voltage supply is adapted to supply higher supply voltages for data processing at higher clock frequencies.
