Techniques for decoupled access-execute near-memory processing include examples of first or second circuitry of a near-memory processor receiving instructions that cause the first circuitry to implement system memory access operations to access one or more data chunks and the second circuitry to implement compute operations using the one or more data chunks.

An apparatus and method for a tensor permutation engine. The TPE may include a read address generation unit (AGU) to generate a plurality of read addresses for the plurality of tensor data elements in a first storage and a write AGU to generate a plurality of write addresses for the plurality of tensor data elements in the first storage. The TPE may include a shuffle register bank comprising a register to read tensor data elements from the plurality of read addresses generated by the read AGU, a first register bank to receive the tensor data elements, and a shift register to receive a lowest tensor data element from each bank in the first register bank, each tensor data element in the shift register to be written to a write address from the plurality of write addresses generated by the write AGU.

System configurations and techniques for implementation of a neural network in neuromorphic hardware with use of external memory resources are described herein. In an example, a system for processing spiking neural network operations includes: a plurality of neural processor clusters to maintain neurons of the neural network, with the clusters including circuitry to determine respective states of the neurons and internal memory to store the respective states of the neurons; and a plurality of axon processors to process synapse data of synapses in the neural network, with the processors including circuitry to retrieve synapse data of respective synapses from external memory, evaluate the synapse data based on a received spike message, and propagate another spike message to another neuron based on the synapse data. Further details for use and access of the external memory and processing configurations for such neural network operations are also disclosed.

Spiking neural network accelerator using external memory

Systems and techniques for neuromorphic accelerator multitasking are described herein. A neuron address translation unit (NATU) may receive a spike message. Here, the spike message includes a physical neuron identifier (PNID) of a neuron causing the spike. The NATU may then translate the PNID into a network identifier (NID) and a local neuron identifier (LNID). The NATU locates synapse data based on the NID and communicates the synapse data and the LNID to an axon processor.

Neuromorphic accelerator multitasking

Systems, apparatuses and methods may provide for a chip that includes a memory array having a plurality of rows corresponding to neurons in a spiking neural network (SNN) and a row decoder coupled to the memory array, wherein the row decoder activates a row in the memory array in response to a pre-synaptic spike in a neuron associated with the row. Additionally, the chip may include a sense amplifier coupled to the memory array, wherein the sense amplifier determines post-synaptic information corresponding to the activated row. In one example, the chip includes a processor to determine a state of a plurality of neurons in the SNN based at least in part on the post-synaptic information and conduct a memory array update, via the sense amplifier, of one or more synaptic weights in the memory array based on the state of the plurality of neurons.

In-memory spiking neural networks for memory array architectures

In an embodiment, a processor includes a sparse access buffer having a plurality of entries each to store for a memory access instruction to a particular address, address information and count information; and a memory controller to issue read requests to a memory, the memory controller including a locality controller to receive a memory access instruction having a no-locality hint and override the no-locality hint based at least in part on the count information stored in an entry of the sparse access buffer. Other embodiments are described and claimed.

System, apparatus and method for selective enabling of locality-based instruction handling

A device is configured to be in communication with one or more host cores via a first communication path. A first set of processing-in-memory (PIM) cores and a second set of PIM cores are configured to be in communication with a memory included in the device over a second communication path, wherein the first set of PIM cores have greater processing power than the second set of PIM cores, and wherein the second communication path has a greater bandwidth for data transfer than the first communication path. Code offloaded by the one or more host cores are executed in the first set of PIM cores and the second set of PIM cores.

In one embodiment, a processor includes: a core including a decode unit to decode a memory access instruction having a no-locality hint to indicate that data associated with the memory access instruction has at least one of non-spatial locality and non-temporal locality; and a locality controller to determine whether to override the no-locality hint based at least in part on one or more performance monitoring values. Other embodiments are described and claimed.

The present disclosure relates to a dynamic random access memory (DRAM) array, which comprises a plurality of bit lines connectable, respectively, to at least two row buffers of the DRAM array. The two row buffers are respectively connectable to data input/output (I/O) lines and are configured to electrically connect the two row buffers to the bit lines and data I/O lines in a mutually exclusive manner.
