Abstract: An apparatus and method are disclosed for transferring data from a first core to a second core of an integrated circuit (IC). The first core includes first and second memory blocks (e.g., first and second portions of a first-in-first-out (FIFO) memory coupled to first and second pre-multiplexers, respectively). The second core includes a multiplexer including first and second inputs coupled to the first and second memory blocks, respectively. Additionally, the second core includes a read controller configured to generate a first read control signal to cause the first and second memory blocks to transfer data to the first and second inputs of the multiplexer, respectively; and generate a second read control signal to cause the multiplexer to transfer data from the first and inputs to an output of the multiplexer.

Abstract: Techniques are described in which a device is configured to retrieve a metadata buffer for rendering a sub-frame of a set of sub-frames for a frame. A data block of a data buffer is configured to store image data for rendering the sub-frame. In response to determining, based on the metadata buffer for rendering the sub-frame, that the sub-frame includes a color pattern, fixed color value, or combination thereof, the device refrains from retrieving the image data from the data block of the data buffer and determines the image data for rendering the sub-frame based on the metadata buffer.

Abstract: The aspects include systems and methods of managing virtual memory page shareability. A processor or memory management unit may set in a page table an indication that a virtual memory page is not shareable with an outer domain processor. The processor or memory management unit may monitor for when the outer domain processor attempts or has attempted to access the virtual memory page. In response to the outer domain processor attempting to access the virtual memory page, the processor may perform a virtual memory page operation on the virtual memory page.
