57 / 382 page  DS13543 Rev 1 57/382 STM32U5Axxx Functional overview 99 3.19 Neo-Chrom GPU (GPU2D) The Neo-Chrom GPU is accelerating operations for graphic effects like rotation, scaling, and perspective correct texture mapping (2.5D). It works together with an optimized software stack designed for state of the art graphic rendering. The GPU2D main features are: • Multi-threaded fragment (pixel) processing core with a VLIW (very-long instruction word) instruction set • Fixed point functional units • Command list based DMAs to minimize CPU overhead • Two 32-bit AHB master interfaces for texture, command list and framebuffer access • 32-bit AHB slave interface for register bank access • Up to 4 general-purpose flags for system-level synchronization • Texture decompression unit with TSC™4 and TSC™6/TSC™6a support The GPU2D also features: • 2D drawing – Pixel/line drawing – Filled rectangles – Triangles, quadrilateral drawing – Anti-aliasing 8xMSAA (multi-sample anti-aliasing) • Image transformations – 3D perspective correct projections – Texture mapping with bilinear filtering or point sampling • Blit support – Rotation, mirroring, stretching (independently on x and y axis) – Source and/or destination color keying – Pixel format conversions Table 13.LPDMA1 channels implementation and usage Channel x Hardware parameters Features dma_fifo_ size[x] dma_ addressing[x] x = 0 to 3 0 0 Channel x (x = 0 to 3) is implemented with: – no FIFO. Only a single source transfer cell is internally registered. – fixed/contiguously incremented addressing Table 14. LPDMA1 autonomous mode and wake-up in low-power modes Feature Low-power modes Autonomous mode and wake-up LPDMA1 in Sleep, Stop 0, Stop 1 and Stop 2 modes |
