  • Image drawing apparatus and display apparatus with increased memory efficiency
    Patent number: 11100904
    Abstract: According to embodiments, an image drawing apparatus includes: an SRAM; and a transaction conversion unit configured to convert a transaction based on a virtual address indicating a pixel position in a storage area of the SRAM into a transaction based on a physical address in the SRAM. When the storage area is divided into a plurality of windows in a row direction and a column direction so that each window includes one or more lines, and an assigned area which is assigned the physical address in the SRAM is set in each of the windows, the transaction conversion unit converts the transaction based on the virtual address into the transaction based on the physical address based on whether the pixel position indicated by the virtual address is in the assigned area.
