Multi-core computer systems with private/shared cache line indicators
According to embodiments described herein, the hierarchical complexity for coherence protocols associated with clustered cache architectures can be encapsulated in a simple function, i.e., that of determining when a data block is shared entirely within a cluster (i.e., a sub-tree of the hierarchy) and is private from the outside. This allows embodiments to eliminate complex recursive coherence operations that span the hierarchy and instead employ simple coherence mechanisms such as self-invalidation and write-through but which are restricted to operate where a data block is shared. Thus embodiments recognize that, in the context of clustered cache hierarchies, data can be shared entirely within one cluster but can be private (unshared) to this cluster when viewed from the perspective of other clusters. This characteristic of the data can be determined and then used to locally simplify coherence protocols. |

Ultra-dense LED projector using thinned gallium nitride
A small projector uses an ultra-dense array of gallium nitride (GaN) LEDs. However, epitaxial growth of GaN typically produces a GaN region that is 5 um or thicker. To achieve high pixel density, the LEDs have small area, so the resulting LED structures are tall and skinny. This is undesirable because it makes further processing more difficult and has higher optical losses. As a result, it is beneficial to reduce the thickness of the GaN region. In one approach, a wafer with the GaN region on substrate is bonded to a backplane wafer containing LED driver circuits. The substrate is then separated from the GaN region, exposing a buffer layer of the GaN region. The GaN region is thinned and then patterned into individual LEDs. Typically, the buffer layer is removed entirely. |

Sensor, apparatus for lidar application and method of background cancellation
Techniques of designing an image sensor particularly useful in lidar applications are described. According to one aspect of the present invention, an image sensor is designed to take advantage of the architecture of CMOS sensor with correlated double sampling, or CDS, to avoid the sensing speed being halved in order to cancel background light interference. It is commonly known that a photosensor is read twice (i.e., first and second readouts) in CDS for removing the inherent noises from the photosensor itself. Instead of subtracting a pixel's dark or reference output level from an actual light-induced signal, a background image is managed to be captured before the second readout of the sensor and subtracted from an actual image, where the actual image is defined to include an target. As a result, the readout speed of an image sensor is maintained while the background light interference is removed. |
