A technique for rendering an under-vehicle view including obtaining a first location of a vehicle, the vehicle having a set of cameras disposed about the vehicle, capturing a set of images; storing images of the set of images in a memory, wherein the images are associated with a time the images were captured, moving the vehicle to a second location, obtaining the second location of the vehicle, determining an amount of time for moving the vehicle from the first location to the second location, generating a set of motion data, the motion data indicating a relationship between the second location of the vehicle and the first location of the vehicle, obtaining one or more stored images from the memory based on the determined amount of time, rendering a view under the vehicle based on the one or more stored images and set of motion data, and outputting the rendered view.

Arbitration and interleaving are performed with respect to memory requests in a memory controller that includes a set of interfaces, each configured to be coupled to a respective one of multiple external requestors, in which each interface receives memory requests from its associated external requestor. The memory controller further includes multiple sets of memory channel queues, one set for each interface, and multiple requestor arbitration modules, each associated with and coupled to a respective one of the multiple sets of memory channels. The memory controller further includes an interconnect coupled to the multiple requestor arbitration modules. The interconnect includes multiple external memory arbitration modules. Each of the requestor arbitration modules applies an arbitration algorithm to arbitrate among the memory requests in the associated set of memory channel queues. Each of the external memory arbitration modules also applies an arbitration algorithm to arbitrate among memory requests presented by the requestor arbitration modules.

Multichannel memory arbitration and interleaving scheme

Techniques including a memory controller with a set of memory channel queues, wherein memory channel queues of the set of memory channel queues correspond to memory channels to access a set of memory modules, a first arbitration module, and a second arbitration module. The memory controller is configured to receive a first memory request from the peripheral and place one or more portions of the first memory request in the memory channel queues of the set of memory channel queues. The first arbitration module is configured to determine an arbitration algorithm, select a first memory channel queue based on the arbitration algorithm, present the one or more portions of the first memory request in the selected first memory channel queue to the second arbitration module, and output the presented one or more portions of the first memory request based on a selection by the second arbitration module.

A method for generating a surround view (SV) image for display in a view port of an SV processing system is provided that includes capturing, by at least one processor, corresponding images of video streams from each camera of a plurality of cameras and generating, by the at least one processor, the SV image using ray tracing for lens remapping to identify coordinates of pixels in the images corresponding to pixels in the SV image.
