Abstract:
A signal processing apparatus has a first memory in which plural pieces of FIR coefficient data used for implementing an FIR filter algorithm are stored, a second memory which stores plural pieces of input data to be subjected to the FIR filter algorithm, and a processor implements the FIR filter algorithm using the plural pieces of FIR coefficient data stored in the first memory and the plural pieces of input data stored in the second memory as many times as the number corresponding to a designated filter order, in which filter algorithm each piece of coefficient data and each piece of input data are multiplied together and resultant products are summed up. The signal processing apparatus is provided, which can implement plural sorts of FIR filter algorithms of filter order which can be changed flexibly.

Claim (Index 6):
The signal processing apparatus according to  claim 4 , wherein the filter algorithm implementing unit comprises:\n a first register which retains in synchronism with the clock the coefficient data output from the first memory; a first selector which selects either one of input data in the current sampling period and the delay data output from the second memory; a second register which retains in synchronism with the clock the data output from the first selector; a multiplier which multiplies the coefficient data output from the first register and the data output from the second register to obtain product data; a third register which retains in synchronism with the clock the product data output from the multiplier; an adder which adds the product data output from the third register and current summed-up data together to obtain sum data; a fourth register which retains in synchronism with the clock the sum data output from the adder; and a second selector which selects either one of data of a value \u201c0\u201d and the sum data output from the fourth register to feed back the selected data as the summed-up data to the adder.
