Techniques related to a data processing engine for an integrated circuit (IC) are described. In an example, a method is provided for vectorized peak detection. The method includes dividing a set of data samples of a data signal, corresponding to a peak detection window (PDW), into a plurality of subsets of data samples each comprising a number of data samples. The method includes performing vector operations on each of the plurality of subsets of data samples. The method includes determining a running index of a sample with a maximum amplitude over the PDW based on the vector operations.

Vectorized peak detection for signal processing

In one embodiment, a matrix multiplication circuit is provided. The circuit includes a plurality of systolic arrays, a pre-processing circuit, and a post-processing circuit. The pre-processing circuit is configured to receive first and second input matrices, and decompose the first input matrix into a plurality of sub-matrices. The pre-processing circuit inputs each of the plurality of sub-matrices to at least a respective one of the plurality of systolic arrays for multiplication with the second input matrix. The post-processing circuit is configured to combine output of the systolic arrays into a result matrix.

Multiplication of matrices using systolic arrays

An apparatus comprises a network physical layer and an activity sensor for sensing a packet and activating the network physical layer from shutdown. The network physical layer decodes a PHY header portion and a media access control header portion of a packet header. A MAC has a fixed hardware media access plane implementing IEEE 802.11 series MAC functionality and couples to a microprocessor. A MAC address parser receives the MAC header portion of the packet, for processing the MAC header portion of the packet, and for activating the MAC from a shutdown in response to recognizing a MAC address within the MAC header portion of the packet, such that the MAC is not activated if the MAC parser does not recognize the MAC address, wherein the MAC is operable, after activation, to perform MAC functionality without the microprocessor and to provide data from the packet to the microprocessor.

Hardware-based packet address parsing for packet reception in wireless networks

Passive listening in wireless communication. An activity sensor device senses a packet. A medium access control (MAC) address parser receives the packet, processes a header of the packet, and activates a MAC device in response to recognizing a MAC address within the header, such that the MAC device is not activated if the MAC address parser does not recognize the MAC address.
