Abstract

Systems, apparatuses, and/or methods may define a priority of image memory traffic based on image sensor protocol metadata. For example, a metadata identifier may identify image sensor protocol metadata corresponding to an image sensor physical layer and/or an image sensor link layer. Moreover, a prioritizer may define a priority of the image memory traffic based on the image sensor protocol metadata. The priority may be used to control client access to dedicated memory and/or to shared memory.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . A system comprising:
 an image sensor to provide image memory traffic,   a metadata identifier to identify image sensor protocol metadata corresponding to one or more of an image sensor physical layer or an image sensor link layer, and   a prioritizer to define a priority of the image memory traffic based on the image sensor protocol metadata.   
     
     
         2 . The system of  claim 1 , wherein the prioritizer is to include one or more of,
 an impact determiner to determine an impact magnitude of the image sensor protocol metadata to define the priority of the image memory traffic, or   an augmenter to augment a priority indicator based on the impact magnitude.   
     
     
         3 . The system of  claim 1 , wherein the image sensor protocol metadata is to include one or more of image sensor physical layer protocol metadata or image sensor link layer protocol metadata, and wherein the prioritizer is to prioritize the image memory traffic based on one or more of the image sensor physical layer protocol metadata or the image sensor link layer protocol metadata. 
     
     
         4 . An apparatus comprising:
 a metadata identifier to identify image sensor protocol metadata corresponding to one or more of an image sensor physical layer or an image sensor link layer, and   a prioritizer to define a priority of image memory traffic based on the image sensor protocol metadata.   
     
     
         5 . The apparatus of  claim 4 , wherein the prioritizer is to include an impact determiner to determine an impact magnitude of the image sensor protocol metadata to define the priority of the image memory traffic. 
     
     
         6 . The apparatus of  claim 4 , wherein the prioritizer is to include an augmenter to augment a priority indicator based on an impact magnitude of the image sensor protocol metadata to define the priority of the image memory traffic. 
     
     
         7 . The apparatus of  claim 6 , wherein the priority indicator is to include memory bus protocol metadata including one or more of a round robin rule, a weight value, a priority value, a deadline, or a buffer occupancy. 
     
     
         8 . The apparatus of  claim 4 , further including one or more of,
 an arbitration controller to control client access to one or more of dedicated memory or shared memory, or   a refresh controller to control refresh of one or more of the dedicated memory or the shared memory.   
     
     
         9 . The apparatus of  claim 4 , wherein the image sensor protocol metadata is to include one or more of image sensor physical layer protocol metadata or image sensor link layer protocol metadata, and wherein the prioritizer is to define the priority of the image memory traffic based on one or more of the image sensor physical layer protocol metadata or the image sensor link layer protocol metadata. 
     
     
         10 . The apparatus of  claim 9 , wherein the image sensor physical layer protocol metadata is to include one or more of physical layer power state mode data, physical layer escape mode data, physical layer clock mode data, physical layer start of line data, or physical layer end of line data, and wherein the image sensor link layer protocol metadata is to include one or more of link layer start of line data, link layer end of line data, link layer start of frame data, or link layer end of frame data. 
     
     
         11 . At least one computer readable storage medium comprising a set of instructions, which when executed by a device, cause the device to:
 identify image sensor protocol metadata corresponding to one or more of an image sensor physical layer or an image sensor link layer; and   define a priority of image memory traffic based on the image sensor protocol metadata.   
     
     
         12 . The at least one computer readable storage medium of  claim 11 , wherein the instructions, when executed, cause the device to determine an impact magnitude of the image sensor protocol metadata to define the priority of the image memory traffic. 
     
     
         13 . The at least one computer readable storage medium of  claim 11 , wherein the instructions, when executed, cause the device to augment a priority indicator based on an impact magnitude of the image sensor protocol metadata to define the priority of the image memory traffic.
