Abstract: In an embodiment, an outer product engine is configured to perform outer product operations. The outer product engine may perform numerous multiplication operations in parallel on input vectors, in an embodiment, generating a resulting outer product matrix. In an embodiment, the outer product engine may be configured to accumulate results in a result matrix, performing fused multiply add (FMA) operations to produce the outer product elements (multiply) and to accumulate the outer product elements with previous elements from the result matrix memory (add). A processor may fetch outer product instructions, and may transmit the instructions to the outer product engine when the instructions become non-speculative in an embodiment. The processor may be configured to retire the outer product instructions responsive to transmitting them to the outer product engine.

Abstract: A hybrid compression method for compressing images is provided. The method identifies a first set of image components to be compressed by a lossy compression format and a second set of image components to be compressed by a lossless compression format. The method then encodes the first set of image components according to the lossy compression format and encodes the second set of image components according to the lossless compression format. The method then generates a compressed structure that includes the lossy-compressed first set of image components and the lossless-compressed second set of image components.

Abstract: The subject technology groups received data in data blocks having a predetermined number of bytes. For each received data block, a compressed data block is written to an output buffer. The compressed data block includes a mask block having a same number of bits as the predetermined number, and a subsequent block. The mask block includes in a same order as bytes within the corresponding data block, a zero corresponding to a zero-byte within the data block, and a one corresponding to each non-zero byte within the data block. The subsequent block includes non-zero bytes within the corresponding data block in a same order as the non-zero bytes within the data block.

Abstract: In an embodiment, a processor supports one or more compression assist instructions which may be employed in compression software to improve the performance of the processor when performing compression/decompression. That is, the compression/decompression task may be performed more rapidly and consume less power when the compression assist instructions are employed then when they are not. In some cases, the cost of a more effective, more complex compression algorithm may be reduced to the cost of a less effective, less complex compression algorithm.

Abstract: Embodiments described herein provide a compressed container format that enables the container to be decrypted and decompressed in a streaming manner. One embodiment provides a container format for encrypted archives in which data is compressed and encrypted in a segmented manner. A segment of the archive can be decompressed, decrypted, and checked for integrity before the entire archive is received. Metadata for the encrypted archive is also encrypted to secure details of data stored within the archive.

Abstract: In an embodiment, a computation engine may perform computations on input vectors having vector elements of a first precision and data type. The computation engine may convert the vector elements from the first precision to a second precision and may also interleave the vector elements as specified by an instruction issued by the processor to the computation engine. The interleave may be based on a ratio of a result precision and the second precision. An extract instruction may be supported to extract results from the computations and convert and deinterleave the vector elements to provide a compact result in a desired order.

Abstract: A novel software updating method is provided. A target file is divided into segments, where some segments are updated by patching, while other segments are updated by archiving. The segmentation of the update allows very large files such as DYLD shared caches to be patched in-place, i.e., by using free space available within the file to perform patching rather than requiring enough free space on disk to store both the new version and the old version of the file. The segmentation of the update also allows each segment to be updated individually by the most optimal update method (copy, patch, or archive) so that the size of the update file can be minimized.

Abstract: In an embodiment, a computation engine may offload work from a processor (e.g. a CPU) and efficiently perform computations such as those used in LSTM and other workloads at high performance. In an embodiment, the computation engine may perform computations on input vectors from input memories in the computation engine, and may accumulate results in an output memory within the computation engine. The input memories may be loaded with initial vector data from memory, incurring the memory latency that may be associated with reading the operands. Compute instructions may be performed on the operands, generating results in an output memory. One or more extract instructions may be supported to move data from the output memory to the input memory, permitting additional computation on the data in the output memory without moving the results to main memory.

Abstract: In an embodiment, a computation engine is configured to perform vector multiplications, producing either vector results or outer product (matrix) results. The instructions provided to the computation engine specify a matrix mode or a vector mode for the instructions. The computation engine performs the specified operation. The computation engine may perform numerous computations in parallel, in an embodiment. In an embodiment, the instructions may also specify an offset with the input memories, providing additional flexibility in the location of operands. More particularly, the computation engine may be configured to perform numerous multiplication operations in parallel and to accumulate results in a result memory, performing multiply-accumulate operations for each matrix/vector element in the targeted locations of the output memory.
