Abstract: A memory array arranged as a plurality of memory cells. The memory cells are configured to operate at a determined voltage. A memory management circuitry coupled to the plurality of memory cells tags a first set of the plurality of memory cells as low-voltage cells and tags a second set of the plurality of memory cells as high-voltage cells. A power source provides a low voltage to the first set of memory cells and provides a high voltage to the second set of memory cells based on the tags.

Abstract: A system includes a random access memory organized into individually addressable words. Streaming access control circuitry is coupled to word lines of the random access memory. The streaming access control circuitry responds to a request to access a plurality of individually addressable words of a determined region of the random access memory by generating control signals to drive the word lines to streamingly access the plurality of individually addressable words of the determined region. The request indicates an offset associated with the determined region and a pattern associated with the streaming access.

Abstract: Embodiments are directed towards a reconfigurable stream switch formed in an integrated circuit. The stream switch includes a plurality of output ports, a plurality of input ports, and a plurality of selection circuits. The output ports each have an output port architectural composition, and each is arranged to unidirectionally pass output data and output control information. The input ports each have an input port architectural composition, and each is arranged to unidirectionally receive first input data and first input control information. Each one of the selection circuits is coupled to an associated one of the output ports. Each selection circuit is further coupled to all of the input ports such that each selection circuit is arranged to reconfigurably couple its associated output port to no more than one input port at any given time.

Abstract: Systems and devices are provided to enable granular control over a retention or active state of each of a plurality of memory circuits, such as a plurality of memory cell arrays, within a memory. Each respective memory array of the plurality of memory arrays is coupled to a respective ballast driver and a respective active memory signal switch for the respective memory array. One or more voltage regulators are coupled to a ballast driver gate node and to a bias node of at least one of the respective memory arrays. In operation, the respective active memory signal switch for a respective memory array causes the respective memory array to transition between an active state for the respective memory array and a retention state for the respective memory array.

Abstract: A device include on-board memory, an applications processor, a digital signal processor (DSP) cluster, a configurable accelerator framework (CAF), and a communication bus architecture. The communication bus communicatively couples the applications processor, the DSP cluster, and the CAF to the on-board memory. The CAF includes a reconfigurable stream switch and data volume sculpting circuitry, which has an input and an output coupled to the reconfigurable stream switch. The data volume sculpting circuitry receives a series of frames, each frame formed as a two dimensional (2D) data structure, and determines a first dimension and a second dimension of each frame of the series of frames. Based on the first and second dimensions, the data volume sculpting circuitry determines for each frame a position and a size of a region-of-interest to be extracted from the respective frame, and extracts from each frame, data in the frame that is within the region-of-interest.

Abstract: Embodiments are directed towards a method to create a reconfigurable interconnect framework in an integrated circuit. The method includes accessing a configuration template directed toward the reconfigurable interconnect framework, editing parameters of the configuration template, functionally combining the configuration template with a plurality of modules from an IP library to produce a register transfer level (RTL) circuit model, generating at least one automated test-bench function, and generating at least one logic synthesis script. Editing parameters of the configuration template includes confirming a first number of output ports of a reconfigurable stream switch and confirming a second number of input ports of the reconfigurable stream switch. Each output port and each input port has a respective architectural composition. The output port architectural composition is defined by a plurality of N data paths including A data outputs and B control outputs. The input port architectural composition is defined by a plurality of M data paths including A data inputs and B control inputs.
