Abstract: The technology provides an efficient delta-of-delta compression process, which is designed to take advantage of large register configurations such as 128-bit or 256-bit registers. The process employs predictors to predict particular data values, such as for a timeseries of data. The timeseries is stored as a vector of points in memory. Predictors leverage instruction size and register size so that data storage is highly efficient, and processing latency is minimized or otherwise reduced. The process can be particularly beneficial for certain architectures, including single instruction, multiple data (“SIMD”) architectures, as it allows for the reuse of operands between iterations. This reduces the number of register loads required by the processing system, such as by omitting one or more load instructions that would otherwise be required. Moreover, decompression of compressed data generated by this approach can be performed very quickly, which can be important for data retrieval.

Abstract: Forces applied to the channel regions of semiconductor slabs in a first direction relative to the semiconductor slab, can create strains in the crystal structure that improve carrier mobility to improve drive strength in the channel region. In a three-dimensional (3D) FET structure, a work function metal layer is provided on opposing faces of semiconductor slabs to cause a force to be exerted on the channel regions in a first direction corresponding to current flow. The force in the first direction is either tensile force or compressive force, depending on a FET type (N or P) employing the semiconductor slab, and is provided to create strain in a crystalline structure of the semiconductor slab to improve carrier mobility in the channel region. Increasing carrier mobility in the channel regions in a 3D FET structure increases drive strength of the 3D FET, which saves area in an integrated circuit.
