    Abstract: Techniques are disclosed relating to securing hardware accelerators used by a computing device. In some embodiments, a computing device includes one or more processors configured to co-execute trusted processes and untrusted processes in an isolated manner that includes implementing a secure environment in which a set of security criteria is enforced for data of the trusted processes. The computing device further includes multiple heterogenous hardware accelerators configured to implement exclaves of the secure environment that extend enforcement of one or more of the set of security criteria within the hardware accelerators for data distributed to the hardware accelerators for performance of tasks associated with the trusted processes.

    Abstract: A device may include a display for displaying an image frame based on warped image data and image processing circuitry to generate the warped image data by warping input image data to account for one or more distortions associated with displaying the image. The image processing circuitry may include a two-stage cache architecture having an first cache and an second cache and warp the input image data by generating mapping data indicative of a warp between the input image space and the output image space and fetching the input image data to populate the first cache. Warping may also include populating the second cache with a grouping of pixel values from the first cache that are selected according to a sliding window that traverses the first cache based on the mapping data and interpolating between pixel values of the grouping to generate pixel values of the warped image data.
