Processing cores with data associative adaptive rounding and associated methods are disclosed herein. One disclosed processing core comprises an arithmetic logic unit cluster configured to generate a value for a unit of directed graph data using input directed graph data, a comparator coupled to a threshold register and a data register, a core controller configured to load a threshold value into the threshold register when the value for the unit of directed graph data is loaded into the data register, and a rounding circuit. The rounding circuit is configured to receive the value for the unit of directed graph data from the arithmetic logic unit cluster and conditionally round the value for the unit of directed graph data based on a comparator output from the comparator.

Processing core with data associative adaptive rounding

A processing core and associated methods for the efficient execution of a directed graph are disclosed. A disclosed processing core comprises a memory and a first data tile stored in the memory. The first data tile includes a first set of data elements and metadata stored in association with the first set of data elements. The processing core also comprises a second data tile stored in the memory. The second data tile includes a second set of data elements. The processing core also comprises an arithmetic logic unit configured to conduct an arithmetic logic operation using data from the first set of data elements and the second set of data elements. The processing core also comprises a control unit configured to evaluate the metadata and control the arithmetic logic unit to conditionally execute the arithmetic logic operation based on the evaluation of the metadata.

Processing core with metadata actuated conditional graph execution

Methods and systems regarding the rapid and efficient compression and decompression of sparse data are disclosed. One method for compressing a set of data from a sparse matrix includes, evaluating a sequence of data entries from the set of data, extracting a sequence of sparse data values from the sequence, extracting a sequence of non-sparse data value run lengths from the sequence, formulating a set of row pointers from the sequence, storing the sequence of sparse data values in a first set of memory addresses, and storing the sequence of non-sparse data value run lengths in a second set of memory addresses. The set of row pointers identify a set of rows of the sparse matrix in both the first and second sets of memory addresses. Rapid decompression can be conducted using the row pointers.

Processing core data compression and storage system

A system includes a power management unit that may be configured to estimate the power consumed by at least a portion of each of one or more processor cores during operation of each processor core. The power management unit may be configured to generate a sum of activity values and normal weight factor values for a predetermined set of signals within each processor core to estimate the power consumed. The power management unit may also be configured to adaptively generate and selectively use new weight factor values to estimate the power consumed based upon a total measured dynamic power consumed by each processor core during operation.
