Systems, apparatus and methods are described including operations for memory access via direct memory access engines, of a Gaussian Mixture Model Accelerator, corresponding to individual data streams.

Gaussian mixture model accelerator with direct memory access engines corresponding to individual data streams

A disclosed speech processor includes a front end to receive a speech input and generate a feature vector indicative of a portion of the speech input and a Gaussian mixture (GMM) circuit to receive the feature vector, model any one of a plurality of GMM speech recognition algorithms, and generate a GMM score for the feature vector based on the GMM speech recognition algorithm modeled. In at least one embodiment, the GMM circuit includes a common compute block to generate feature a vector sum indicative of a weighted sum of differences squares between the feature vector and a mixture component of the GMM speech recognition algorithm. In at least one embodiment, the GMM speech recognition algorithm being modeled includes a plurality of Gaussian mixture components and the common compute block is operable to generate feature vector scores corresponding to each of the plurality of mixture components.

Flexible architecture for acoustic signal processing engine

Some demonstrative embodiments include devices, systems and/or methods of turbo decoding. For example, a device may include a turbo decoder to decode a turbo-encoded input according to a turbo code, the turbo-encoded input including a plurality of soft-decision information-bit values and a plurality of soft-decision parity-bit values corresponding to the soft-decision information bit values, wherein the turbo decoder is to output a plurality of extrinsic soft-decision parity-bit values corresponding to the plurality soft-decision parity-bit values. Other embodiments are described and claimed.
