Abstract: The present disclosure is directed to systems and methods of bit-serial, in-memory, execution of at least an nth layer of a multi-layer neural network in a first on-chip processor memory circuitry portion contemporaneous with prefetching and storing layer weights associated with the (n+1)st layer of the multi-layer neural network in a second on-chip processor memory circuitry portion. The storage of layer weights in on-chip processor memory circuitry beneficially decreases the time required to transfer the layer weights upon execution of the (n+1)st layer of the multi-layer neural network by the first on-chip processor memory circuitry portion. In addition, the on-chip processor memory circuitry may include a third on-chip processor memory circuitry portion used to store intermediate and/or final input/output values associated with one or more layers included in the multi-layer neural network.

Abstract: The present disclosure is directed to systems and methods of implementing a neural network using in-memory mathematical operations performed by pipelined SRAM architecture (PISA) circuitry disposed in on-chip processor memory circuitry. A high-level compiler may be provided to compile data representative of a multi-layer neural network model and one or more neural network data inputs from a first high-level programming language to an intermediate domain-specific language (DSL). A low-level compiler may be provided to compile the representative data from the intermediate DSL to multiple instruction sets in accordance with an instruction set architecture (ISA), such that each of the multiple instruction sets corresponds to a single respective layer of the multi-layer neural network model. Each of the multiple instruction sets may be assigned to a respective SRAM array of the PISA circuitry for in-memory execution. Thus, the systems and methods described herein beneficially leverage the on-chip processor memory circuitry to perform a relatively large number of in-memory vector/tensor calculations in furtherance of neural network processing without burdening the processor circuitry.

Abstract: Disclosed is a system and device and related methods for data manipulation, especially for SIMD operations such as permute, shift, and rotate. An apparatus includes a permute section that repositions data on sub-word boundaries and a shift section that repositions the data distances smaller than the sub-word width. The sub-word width is configurable and selectable, and the permute section and shift section may operate on different boundary widths. In a first stage, the permute section repositions the data at the nearest sub-word boundary and, in a second stage, the shift section repositions the data to its final desired position. The shift section includes multi-stages set in a logarithmic cascade relationship. Additionally, each shifter within each of the multi-stages is highly connected, allowing fast and precise data movements.

Abstract: For one disclosed embodiment, a converter converts 2N-bit data into an N-bit value indicating a number of bits in the data that have a predetermined logical value. The converter includes N comparators, each determining whether the number of bits in the data having the predetermined logical value exceeds a respective one of a plurality of reference values. The N-bit value is generated based on the outputs of the comparators. For another disclosed embodiment, a first delay element delays a signal based on a number of bits in a data value having a predetermined logical value, and a second delay element delays the signal based on a number of bits in a reference value having the predetermined logical value. A comparator then generates a bit value based on the delayed signals.
