    Abstract: In one embodiment, one or more control units may store a position tracker associated with a first window of memory blocks and allow a first processing unit to write data within the first window. The control units may receive, from a second processing unit, a request for reading data with a memory-reading address, compare the memory-reading address to a first starting address of the first window, and prevent the second processing unit from reading the data when the memory-reading address is greater than or equal to the first starting address of the first window. The control units may store, when the data writing process is complete, an updated position tracker of a second window of memory blocks and allow the second processing unit to read the data based on a determination that the memory-reading address is less than a second starting address of the second window.

    Abstract: In an embodiment, a method involves accessing a first pixel block of an image, the first pixel block comprising pixels, each associated with multiple pixel components, determining whether to separately or jointly encode the multiple pixel components of each of the pixels of the first pixel block, determining that the multiple pixel components of each of the pixels in the first pixel block are to be jointly encoded based on (1) determining, based on the multiple pixel components of each of the pixels, a line defined within a three-dimensional coordinate system in which each of the pixels is represented as a three-dimensional point and (2) determining that the line satisfies a predetermined criteria, and encoding the multiple pixel components of each of the pixels in the first pixel block as a single quantized value based on a projection of the three-dimensional point associated with that pixel onto the line.

    Abstract: Disclosed herein includes a system, a method, and a device for compressing image data. The device includes one or more processors, coupled to memory, configured to identify a plurality of sub-blocks of a block of image data including a first sub-block and a second sub-block. The one or more processors are configured to identify a first data characteristic of data of the first sub-block and a second data characteristic of data of the second sub-block, determine a first compression technique based at least on the first data characteristic of the first sub-block, determine a second compression technique based at least on the second data characteristic of the second sub-block, and compress the first sub-block using the first compression technique and the second sub-block using the second compression technique.
