Abstract: An apparatus and method for Fast Fourier Transform (FFT) address generation is disclosed. The apparatus may include a counter circuit and circuitry configured to load an initial value into a counter circuit. The circuitry may be further configured to generate first and second output values by formatting a current value of the counter, and increment the current value of the counter circuit by an increment value to generate a next value. The circuitry may also be configured to modify the increment value in response to a determination that the next value is equal to a target value.

Abstract: Systems and methods are disclosed for a server generating a plurality of proxy prediction models for each of a plurality of applications for use by client devices. Providing a prediction model based on a data distribution that more closely matches the user private data of the actual user of the client device, as opposed to a generic model, can improve the accuracy of predictions and improve the benefits to the user of the client device. The plurality of prediction models are generated by a server and provided to a plurality of clients. For a particular application, a client device can use previously collected private user data to select one of the plurality of prediction models for the application as being a closest matching prediction model to use for a particular user.
