Digital signal processor and method for processing data with a digital signal processor

Digital signal processor with memory registers (3), at least one processing unit (1) and at least one switching unit (2) which is connected to the at least one processing unit (1) and memory registers (3), wherein the digital signal processor is adapted such that the at least a processing unit (1) to memory register (3) for reading and / or writing the memory contents access, characterized in that at least two storage registers (3) are connected to at least one shift register chain (4-6), wherein the digital signal processor is set up such that the at least one processing unit (1) associated with the in each case to a shift register chain (4-6) storage register (3) can access only the first and last storage register within the shift register chain (4-6), wherein said first storage register only described is and is only read from the last memory register, and belonging to each of the a shift register chain (4-6) storage registers (3) only the first and last storage register within the shift register chain (4-6) with a switching unit (2).
