Abstract: A processor and a method for designating a demotion target to demote the demotion target from an in-core cache structure to an out-of-core cache structure is shown. In response to a cache data demotion instruction supported by an instruction set architecture, a first core of a processor operates a decoder to decode the cache data demotion instruction into microinstructions. According to the microinstructions, a demotion target designation request is transferred to a last-level cache (LLC) through a memory order buffer to drive the LLC to query an out-of-core cache table. According to the demotion target's cache status in the first core obtained from the out-of-core cache table, the LLC outputs a snoop request to the first core to snoop on the demotion target and demote the demotion target from the in-core cache structure of the first core to the LLC.

Abstract: In various examples, to support training a deep neural network (DNN) to predict a dense representation of a 3D surface structure of interest, a training dataset is generated using a parametric mathematical modeling. A variety of synthetic 3D road surfaces may be generated by modeling a 3D road surface using varied parameters to simulate changes in road direction and lateral surface slope. In an example embodiment, a synthetic 3D road surface may be created by modeling a longitudinal 3D curve and expanding the longitudinal 3D curve to a 3D surface, and the resulting synthetic 3D surface may be sampled to form a synthetic ground truth projection image (e.g., a 2D height map). To generate corresponding input training data, a known pattern that represents which pixels may remain unobserved during 3D structure estimation may be generated and applied to a ground truth projection image to simulate a corresponding sparse projection image.
