Abstract: A channel driver circuit includes a differential module and a driver module. In some examples, the channel driver circuit also includes a sigma-delta module. The differential module receives, via a single node of a load, a channel driving signal that is provided to the load at the single node (e.g., that is based on an electrical characteristic of the load) and generates an analog error signal that is based on the channel driving signal and a reference signal. The driver module is coupled to the differential module and generates the channel driving signal based on the analog error signal or a digital error signal corresponding to the analog error signal and transmits the channel driving signal via the single node to the load. The channel driver circuit simultaneously transmits the channel driving signal to the load at the single node and senses the channel driving signal at the single node.

Cache lines are erasure encoded to be stored in one or more blast zones with at least two nodes in a blast zone storing respective portions of a cache line and at least one node in the blast zone storing a parity portion. In one aspect, it is determined that data stored in one or more nodes of a blast zone needs to be reconstructed and stored in one or more spare nodes designated to replace the one or more nodes. Erasure decoding is performed using data from one or more other nodes in the blast zone to reconstruct the data for storage in the one or more spare nodes.

Abstract: A new approach is proposed to support systematic generation of a set of test cases/stimuli used to validate a multiprocessor system having a plurality of processors that supports memory coherence. A pair of two of the plurality of processors is first selected for testing one pair at a time, wherein a first of the pair is a requester requesting access to a cache associated with a second of the pair, which is a snooped requester. The test cases are automatically generated based on an algorithm-driven script, wherein the set of test cases includes an instruction set and all valid combinations of cache states of the processors. The instruction set is then executed by the pair of processors to validate memory coherence of the pair of processors. The above process is repeated so that each processor of the plurality of processors is included for memory coherence testing at least once.

Abstract: Methods and apparatuses for hierarchical partitioning of operators of a neural network for execution on an acceleration engine are provided. Neural networks are built in machine learning frameworks using neural network operators. The neural network operators are compiled into executable code for the acceleration engine. Development of new framework-level operators can exceed the capability to map the newly developed framework-level operators onto the acceleration engine.

The hierarchical partitioning can identify operators that are supported by a compiler for execution on the acceleration engine, operators to be compiled for execution on a host processor, and operators to be executed on the machine learning framework.
