Abstract
A stream processor for an implantable medical device provides rapid computation using simple architecture and low power in which each input data sample is processed in parallel by a separate and independent central processing unit executing similar or identical kernel code consisting of the following elements. A housing contains a power source. A controller with memory coupled to the power source. A first physiological sensing apparatus and at least a second physiological sensing apparatus is coupled to the controller. A first stream processing element is coupled to the first physiological sensor and coupled to the controller. At least a second stream processing element is coupled to the second physiological sensor and coupled to the controller.
