It's been a while since my last performance blog, but one of those lunchtime coffee discussions about a blog I'd like to write was turned into a working tech demo by wasimabbas overnight, so thanks…
Mali Performance 6: Efficiently Updating Dynamic Resources
My last blog looked at some of the critical areas which an application has to implement efficiently to get best performance out of 3D content, such as broad-brush culling of large sections of a scene…
Mali Performance 5: An Application's Performance Responsibilities
Previous blog in the series: Mali Performance 4: Principles of High Performance RenderingWelcome to the next instalment of my blog series looking at graphics rendering performance on Mali GPUs using OpenGL…
Mali Performance 4: Principles of High Performance Rendering
Previous blog in the series: Mali Performance 3: Is EGL_BUFFER_PRESERVED a good thing?In my previous blogs in this series I have looked at the bare essentials for using a tile-based rendering architecture…
Mali Performance 3: Is EGL_BUFFER_PRESERVED a good thing?
Previous blog in the series: Mali Performance 2: How to Correctly Handle Framebuffers
This week I'm finishing off my slight diversion into the land of application framebuffer management with an analysis…
Mali Performance 2: How to Correctly Handle Framebuffers
This week I look at how, and more importantly when, the Mali driver stack turns OpenGL ES API activity into the hardware workloads needed for rendering.
Mali Performance 1: Checking the Pipeline
Mali performance: In this blog we will look at debugging issues around macro-scale pipelining, the means by which we keep the GPU busy and some of the common reasons for that frame level pipeline to stall…
The Mali GPU: An Abstract Machine, Part 3 - The Midgard Shader Core
In this blog I will finish the construction of this abstract machine, forming the final component: a stereotypical Mali Midgard GPU programmable core.
The Mali GPU: An Abstract Machine, Part 2 - Tile-based Rendering
This blog continues the development of this abstract machine, looking at the tile-based rendering model of the Arm Mali GPU family. I’ll assume you've read the blog on pipelining; if you haven’t I suggest…
The Mali GPU: An Abstract Machine, Part 1 - Frame Pipelining
We will explore the fundamental macro-scale architectural structures and behaviors developers have to worry about, how this translates into possible problems which can be triggered by content.
How do I do <x> in assembler?
One of the most common classes of question in the ARM community which I answer is "How do I do <x> in ARM assembler?". While I am always happy to answer these questions, I thought it would be useful to…
