WebFIR designs can be implemented using a circular buffer. The basic idea in memory optimization is to reduce data movement as much as possible, at the expense of more … WebWe discuss the concept of circular buffersand their use in implementing delays and FIR filters. We present a systematic treatment of the subject and carry it on to the remainder of the book. The use of circular delay-line buffers is old, dating back at least 25 years with its application to computer music. However, it has not been treated
