Abstract: A data transmitter is provided which performs digital to analog conversion, convolution with an arbitrary finite impulse response, and smoothing of the output functions without requiring a separate anti-aliasing low pass filter. To implement the data transmitter, a digital input data value is convolved with a desired impulse response. The coefficients of the desired finite impulse response filter are chosen to create a first or second derivative of an output of the data transmitter. Then, the derivative is integrated so that a resulting signal output from the data transmitter is a smooth signal which does not require further filtering.

Abstract: An apparatus and method are implemented to track and manage system cycles stolen from a data processor by other processors in a multiprocessor data processor system. The apparatus and method maximize data throughput and minimize unused cycle resources within the multiprocessor data processing system.
