ABSTRACT:
Speech Label Accelerators (SLAs) are provided that comprise an indirect memory, atom value memory, and adder circuitry. Optionally, the SLAs also comprise an accumulator, a load/accumulate multiplexer (mux), and a control unit. There are a variety of different configurations for the adder circuitry, and a configuration can be selected based on speed, power, and area requirements. A number of techniques are provided that allow a system having an SLA to handle more dimensions, atoms, or both than the SLA was originally designed for. A “zig-zag” method is provided that speeds processing in a system when using more dimensions than the SLA was originally designed for. Generally, the kernels used by the SLA will be Gaussian and separable, but non-Gaussian kernels and partially separable kernels may also be used by the SLA.
