Abstract
In the described examples, a video integrated circuit (IC) chip includes a video input port (VIP) that receives a video stream. The video IC chip also includes a processing unit coupled to a non-transitory memory and is configured to detect the presence of a data stream provided to the VIP, cause the VIP to switch a target partition for the data stream from a given partition in the memory to another partition in the memory and to write the data stream to the other partition in the memory.
Claims20
An integrated circuit chip comprising:
- an input port configured to receive a set of data;
- a video input circuit coupled to the input port and configured to receive the set of data, wherein the video input circuit includes a direct memory access (DMA) circuit;
- and
- a memory coupled to the DMA circuit that includes a first partition and a second partition;
- wherein the DMA circuit is configured to:
- determine whether the set of data includes video data;
- based on the set of data including video data, write the set of data to the first partition;
- and
- based on the set of data not including video data, write the set of data to the second partition.
6 more elements
A system comprising:
- a first integrated circuit chip that includes:
- a first output port configured to provide a set of data;
- and
- a second output port configured to provide a control signal that indicates whether the set of data includes video data;
- and
- a second integrated circuit chip that includes:
- a first input port configured to couple to the first output port to receive the set of data;
- a second input port configured to couple to the second output port to receive the control signal;
- a video input circuit coupled to the first input port and the second input port that includes a direct memory access (DMA) circuit;
- and
- a memory coupled to the DMA circuit that includes a first partition and a second partition;
- wherein the DMA circuit is configured to:
- determine based on the control signal whether the set of data includes video data;
- based on the set of data including video data, write the set of data to the first partition;
- and
- based on the set of data not including video data, write the set of data to the second partition.
13 more elements
A method comprising:
- receiving a set of data at an input port;
- determining whether the set of data includes video data;
- determining whether to store the set of data in a first partition of a memory or a second partition of the memory based on whether the set of data includes video data;
- and
- storing the set of data in the memory.
