摘要： Methods, systems, and apparatus, including computer-readable storage media for hardware compression and decompression. A system can include a decompressor device coupled to a memory device and a processor. The decompressor device can be configured to receive, from the memory device, compressed data that has been compressed using an entropy encoding, process the compressed data using the entropy encoding to generate uncompressed data, and send the uncompressed data to the processor. The system can also include a compressor device configured to generate, from uncompressed data, a probability distribution of codewords, generate a code table from the probability distribution, and compress incoming data using the generated code table.

摘要： Aspects of the disclosure include methods, systems, and apparatus, including computer-readable storage media for multi-mode integrated circuits with balanced energy consumption. A method includes determining, by one or more processors and based at least on a maximum energy threshold for planned multi-mode system having one or more processing units, a respective number of operations that can be performed per clock cycle by the processing units for each operating mode. The system is configured to consume the same amount of energy per clock cycle in each operating mode, but perform more operations in operating modes corresponding to operations performed on smaller bit-width operands.

摘要： Aspects of the disclosure provide for methods, systems, and apparatuses, including computer-readable storage media, for sparse matrix multiplication. A system for matrix multiplication includes an array of sparse shards. Each sparse shard can be configured to receive an input sub-matrix and an input sub-vector, where the input sub-matrix has a number of non-zero values equal to or less than a predetermined maximum non-zero threshold. The sparse shard can, by a plurality of multiplier circuits, compute one or more products of vector values multiplied with respective non-zero values of the input sub-matrix. The sparse shard can generate, as output to the sparse shard and using the one or more products, a shard output vector that is the product of applying the shard input vector to the shard input matrix.
