Abstract: Systems and methods related to processors with descriptor table instruction circuitry are disclosed herein. A processor may be defined by an instruction set including an instruction. The processor may comprise: a set of data structures stored in a memory, a configuration register storing a set of characteristics of the set of data structures, and circuitry configured to execute an instruction having a syntax that includes an address in an address space of the data structures. Execution of the instruction may include using the address in the address space of the data structures and the information stored in the configuration register to calculate an address in the address space of the memory. This alleviates the burden of programming a computation in that the address space of the data structures is a step closer to the application level of the computation.

Abstract: A processing core and associated methods for the efficient execution of a directed graph are disclosed. A disclosed processing core includes a memory and a first data tile stored in the memory.

The rounding circuit is configured to receive the value for the unit of directed graph data from the arithmetic logic unit cluster and conditionally round the value for the unit of directed graph data based on a comparator output from the comparator.

Abstract: Methods and systems for the accelerated execution of a directed graph are disclosed. The execution can involve the generation of an inference from a set of inputs provided to an artificial neural network. In a specific example, a method for executing a directed graph includes receiving at least two batches of indices. The batches of indices, when used to access a set of embeddings, provide at least two batches of embedding outputs and execute a layer of the directed graph. The method further includes accessing the set of embeddings using the at least two batches of indices. The method further includes rearranging, based on a set of latencies for the accessing step, the at least two batches of embedding outputs into at least two batches of rearranged embeddings. The method further includes providing the at least two batches of rearranged embeddings to a subsequent layer of the directed graph.
