Abstract: Approaches are provided for implementing hardware-software collaborative address mapping schemes that enable mapping data elements which are accessed together in the same row of one bank or over the same rows of different banks to achieve higher performance by reducing row conflicts. Using an intra-bank frame striping policy (IBFS), corresponding subsets of data elements are interleaved into a single row of a bank. Using an intra-channel frame striping policy (ICFS), corresponding subsets of data elements are interleaved into a single channel row of a channel. A memory controller utilizes ICFS and/or IBFS to efficiently store and access data elements in memory, such as processing-in-memory (PIM) enabled memory.

In response to detecting the condition, the logic remaps a logical address of at least one currently used compute unit to a different physical address that corresponds to the replacement compute unit and causes the replacement compute unit to carry out neural network operations.
Abstract: A system for performing a scan test of a processor core includes a scan test module and a processor including a processor core and an input/output die, where the input/output die is coupled to the processor core. The scan test module transmits, in parallel to the input/output die, scan test input data.

A serializer/deserializer module of the processor core receives the serialized scan test input data, deserializes the input data, receives result data generated in dependence upon the input data, serializes the result data, and transmits the serialized result data to the input/output die. The input/output die serializer/deserializer module receives the result data, deserializes the result data, and provides the result data to the scan test module. Error detection can be carried out through redundancy.
