Processing input data for transmittal to a data consumer such as an artificial intelligence engine is performed by arranging the input data into a uniform structure made up of sticks of data combined to form pages of sticks. A stick is any well-sized set of input data elements whereby the size of the stick is fixed. A masking pattern is established for sticks of data having certain ranges of invalid data for consumption of partial sticks while maintaining validity of the input data being transferred. The mask pattern is derived based on set-active-mask-and-value (SAMV) instructions. The derived mask pattern is carried forward for subsequent load instructions to the data consumer.

Padding input data for artificial intelligence accelerators

Embodiments for providing enhanced multicast data transfer for ring topology based artificial intelligence systems are disclosed. Multicast data is sent to a plurality of disjointed cores in a multicast group according to a first multicast mode, a second multicast mode, or a third multicast mode, where the first multicast mode sends a first half the multicast data on first multicast ring and a second half on a second multicast ring, the second multicast mode sends the multicast data on either the first multicast ring or the second multicast ring, and the third multicast mode replicates the multicast data and sends the multicast data to both the first multicast ring and the second multicast ring.
