ABSTRACT:
A processor comprises an arithmetic unit for processing operands, a register memory for storing operands with a register memory space and a register memory configuration unit. The register memory configuration unit is designed to configure the register memory such that memory space in the register memory is assigned to operands, and that memory space in the register memory that is not assigned to operands will be made available for other data than the operands. Thereby, on the one hand the number of operand transfers between an external bus and the arithmetic unit is decreased, since as many operands as possible are stored in the register memory, while on the other hand, when part of the register memory is not needed for storage of operands, this part will not be idle but made available for other data, so that the memory resources of the processors are always utilized optimally.
