Zero-Delay large signal convolution using multiple processor architectures

Zero latency convolution typically uses the Direct Form approach, requiring a large amount of computational resources for every additional sample in the impulse response. A number of methods have been developed to reduce the computational cost of very large signal convolution. However these all introduce latency into the system. In some scenarios this is not acceptable and must be removed. Modern computer systems hold multiple processor architectures, with their own strengths and weaknesses for the purpose of convolution. This paper shows how correctly combining these processors can lead to a powerful system which can be deployed for real-time, zero-latency large signal convolution.
