Latest Patents

One of Hema's latest patents is focused on a streaming transfers and ordering model. This innovation introduces a hardware/software interface for asynchronous data movement between off-core memory and core-local memory, referred to as 'stream transfers'. The stream transfers enable software to express common data-movement patterns more efficiently, particularly in sparse workloads. Direct stream instructions are processed in order, while indirect stream instructions utilize an offset list for ordered processing. A sync flag is updated to indicate monotonic incremental progress for the stream.

Another notable patent is for a programmable accelerator designed for data-dependent, irregular operations. This accelerator features a programmable engine that efficiently executes dynamic and memory-bound computations on-chip. It works in conjunction with a co-processor that accelerates operations predictable in computational load and behavior during design and fabrication.
