1. A storage-efficient method for processing frame data, comprising: receiving, from a first processing node in a series of processing nodes implemented by one or more computing devices, data at an input buffer associated with a second processing node in the series, wherein the second processing node in the series is to perform an operation that requires an input that is a block of frame data of a first predetermined size to generate a block of frame data of a second predetermined size, and the first and second predetermined sizes each comprise a plurality of frame data samples; determining, by the one or more computing devices, that a size of the data in the input buffer is equal to the first predetermined size; and in response to determining that the size of the data in the input buffer is equal to the first predetermined size, causing, by the one or more computing devices, the second processing node to operate on the frame data in the input buffer to generate a block of frame data of the second predetermined size.
