Abstract
A digital signal processor includes a computation block with an arithmetic logic unit, a multiplier, a shifter and a register file. The computation block includes a plurality of registers for storing instructions and operands in a bit format as a continuous bit stream, and utilizes a bit transfer mechanism for transferring in a single cycle a bit field of an arbitrary bit length between the plurality of registers and the shifter. The plurality of registers may be general purpose registers located in the register file. The register file may further include at least one control information register for storing control information used by the bit transfer mechanism.
