ABSTRACT:
A coefficient data transfer processing method for a digital signal processor which has a coefficient address pointer independent of a program counter, whereby a processing program and coefficient data are transferred and supplied from a microcomputer determination, whether an instruction is a read instruction of the coefficient data to execute a read cycle steal or with is made; a value of a program counter with is made; when it is the read instruction, new coefficient data is transferred from the microcomputer to a transfer buffer at an instruction read stage and instruction decode stage in a processing unit; and the coefficient data stored in the transfer buffer is written into a coefficient data memory by the read cycle steal at an execute stage in the same processing unit.
