ABSTRACT:
A method of processing audio signals is comprised of reading samples of digitally stored audio signals from a first source memory, performing a bit block transfer (BitBLT) of the samples to a register of an arithmetic and logic unit (ALU), reading an array of coefficient signals (coefficients), performing a BitBLT of the coefficients to a register of the ALU, operating on the bit block transferred samples and coefficients together and storing resulting samples in a destination memory, whereby the stored resulting samples can be further accessed for audio reproduction, further processing, permanent storage or transmission.
