Synchronized data chaining using on-chip cache

A system-on-chip comprising:

• one or more processing devices;
• and
• one or more non-transitory machine-readable storage devices storing instructions that are executable by the one or more processing devices to cause performance of operations comprising:
• generating, by an image sensor of a computing device, frame data comprising sub-frames of image pixel data;
• providing, by a first resource of the system-on-chip, the frame data to at least one second resource of the system-on-chip, wherein the frame data is provided to the at least one second resource using an elastic memory buffer and a first data path included in the system-on-chip;
• providing, by the first resource of the system-on-chip, a token to the at least one second resource of the system-on-chip, wherein the token is provided to the at least one second resource using a second data path included in the system-on-chip;
• and
• using, by a processor of the system-on-chip, at least the token provided using the second data path to:
• i) synchronize production of sub-frames of image pixel data provided by the first resource to the at least one second resource;
• and
• ii) synchronize consumption of the sub-frames of image pixel data received by the at least one second resource from the elastic memory buffer.
