Specifications
The Arm Mali-G31 GPU is an ultra-efficient GPU based on the Mali Bifrost architecture. Bringing the benefits of Bifrost to a different tier of device, Mali-G31 builds on the success of the previous ultra efficient products in the Mali-400 Utgard series. With significant energy and area savings compared to the next level of device, plus support for the very latest APIs, Mali-G31 is the GPU of choice for cost constrained devices.
Arm Mali-G31 GPU
| Features | Value | Description |
|---|---|---|
| Anti-Aliasing | 4x MSAA 8x MSAA 16x MSAA |
4x Multi-Sampling Anti-Aliasing (MSAA) with minimal performance drop. |
| API Support |
OpenGL® ES 1.1, 2.0, 3.2 Vulkan 1.2 OpenCL™ 1.1, 1.2, 2.0 Full Profile, RenderScript |
Full support for next-generation and legacy 2D/3D graphics applications. |
| Bus Interface | AMBA®4 ACE-LITE and AXI | Compatible with a wide range of bus interconnect and peripheral IP. |
| L2 Cache | Configurable |
8KB for MP1. 32KB-64KB for MP2. |
| Memory System | Virtual Memory | Built-in Memory Management Unit (MMU) to support virtual memory. |
| Scalability |
1 uni-pixel core or dual-pixel core | Optimized for high area and energy efficiency to address mainstream device requirements. |
| Adaptive Scalable Texture Compression (ASTC) | Low dynamic range (LDR) and high dynamic range (HDR). Supports both 2D and 3D images |
ASTC offers a number of advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use. |
| Arm Frame Buffer Compression (AFBC) |
Version 1.2 4x4 pixel block size |
AFBC is a lossless image compression format that provides random access to pixel data to a 4x4 pixel block granularity. It is employed to reduce memory bandwidth both internally within the GPU and externally throughout the SoC.
|
| Transaction Elimination | 16x16 pixel block size | Transaction Elimination spots the identical pixel blocks between two consecutive render targets and performs a partial update to the frame buffer with the changed pixel blocks only, which reduces memory bandwidth and thus energy. |
Performance - Mali-G31
| Features | Value | Description |
| Frequency | 650 MHz | in 28nm HPM |
| Pixel/Texturing Throughput | 1.3 Gpix/s | in 28nm HPM |
