Abstract: A canary update method according to some embodiments is disclosed. The canary update method includes executing, by a processor configured to process tasks including the canary, computer program instructions to perform operations including extracting, by a processor, a first value from an array including N values, setting the canary to the first value, determining that the canary is updated based on a canary flag value of a first task, extracting, when determined that the canary is updated, a second value from the array, and updating the canary of the first task to the second value. The processor is configured to access a memory through a mapping circuit, and the mapping circuit includes mapping information between a physical memory region in the memory corresponding to the first task and a virtual memory region associated with the mapping circuit.

Abstract: Disclosed are an image processing device and an image processing method performing a slice-based compression. The image processing method includes applying a first compression method to some slices of a first frame image including first to N-th slices (N is an integer of 2 or greater) to generate an I-slice, applying a second compression method to the other slices of the first frame image to which the first compression was not applied to generate a plurality of P-slices, and transmitting less than N packets including the generated I-slice and the generated P-slices with respect to the first frame image.
