摘要: The present disclosure is directed to systems and methods of implementing an analog neural network using a pipelined SRAM architecture (“PISA”) circuitry disposed in on-chip processor memory circuitry. The on-chip processor memory circuitry may include processor last level cache (LLC) circuitry. One or more physical parameters, such as a stored charge or voltage, may be used to permit the generation of an in-memory analog output using a SRAM array. The generation of an in-memory analog output using only word-line and bit-line capabilities beneficially increases the computational density of the PISA circuit without increasing power requirements. Thus, the systems and methods described herein beneficially leverage the existing capabilities of on-chip SRAM processor memory circuitry to perform a relatively large number of analog vector/tensor calculations associated with execution of a neural network, such as a recurrent neural network, without burdening the processor circuitry and without significant impact to the processor power requirements.

摘要: Some implementations disclosed herein provide techniques and arrangements for provisioning keys to integrated circuits/processors. A processor may include physically unclonable functions component, which may generate a unique hardware key based at least on at least one physical characteristic of the processor. The hardware key may be employed in encrypting a key such as a secret key. The encrypted key may be stored in a memory of the processor. The encrypted key may be validated. The integrity of the key may be protected by communicatively isolating at least one component of the processor.

摘要: A method and apparatus for an address generation circuit. In one embodiment, the method includes computing a carry-in for at least one group of a predetermined number of bits of a propagate and a generate signal formed from a plurality of logical address components. Once the carry-in is computed, a plurality of conditional sums are generated for a logic 0 carry-in and a logic 1 carry-in. Subsequently, a sum is selected from the plurality of conditional sums to form a first portion of an effective address from the logical address components in a first stage and a second portion of the effective address in a second stage. In one embodiment, a fully dynamic high-performance sparse tree adder circuit that generates one in four carries, is used to form an address generation circuit, in accordance with one embodiment. Other embodiments are described and claimed.
