Abstract
A microprocessor structure and a method for implementing digital filter operations are disclosed, which utilize an increment/decrement unit, and an accumulator unit and a register set which are already existing in a microprocessor, to provide finite impulse response digital filter and inner product operations. With the increment/decrement unit, when a finite impulse response digital filter operation is executed, it is able to automatically move the data into a memory, so that when a next operation is executed, it is able to immediately perform the operation simply by writing new data and setting pointers, whereby the microprocessor can efficiently perform the operations of digital signal processing.
