A hardware accelerator for an object detection network and a method for detecting an object are provided. The present disclosure provides robust object detection that advantageously augments traditional deterministic bounding box predictions with spatial uncertainties for various computer vision applications, such as, for example, autonomous driving, robotic surgery, etc.

Object detection network with spatial uncertainty

A bidirectional communications link between a master device and a slave device includes first endpoint circuitry coupled to the master device generating forward data packets, second endpoint circuitry coupled to the slave device for receiving reverse data packets, and bidirectional communication circuitry for transferring forward data packets from the first endpoint circuitry to the second endpoint circuitry and reverse data packets from the second endpoint circuitry to the first endpoint circuitry. In response to a power down condition requiring a power down of at least one of the first endpoint circuitry and the second endpoint circuitry, performance of said power down is deferred until both said outstanding forward credit signal and said outstanding reverse credit signal have been de-asserted.

Apparatus and method for providing a bidirectional communications link between a master device and a slave device

A system-on-chip integrated circuitincludes a packet transmitterfor generating data packets to be sent via a communication circuitto a packet receivercontaining a buffer circuit. A transmitter counterstores a transmitter count value counting data packets sent. A receiver counterstores a receiver count value tracking data packets emptied from the buffer circuit. A comparison circuitryis used to compare the transmitter count value and the receiver count value to determine whether or not there is storage space available within the buffer circuitto receive transmission of further data packets. The packet transmitteroperates in a transmitter clock domain that is asynchronous from a receiver clock domain in which the packet receiver operates. One of the count values is passed across this asynchronous clock boundary in order that the comparison may be performed and flow control exercised.
