GPU Memory System Design Architect

ARM Holdings Inc

Don't forget to mention FPGAjobs in your application. We are a small team, and these mentions are a huge help to us!

Job Overview:

There are not many people in the world that can claim to be an expert on designing memory systems. If you possess such rare skills, then we hope you will consider joining us in the GPU Hardware team as our new GPU Memory System Design Architect.


Below follows some typical problems our team is working on solving every day. We hope you find them intriguing!

Problem 1) Make a scalable memory system

We make GPUs for small screens such as watches, and for large screens found in laptops, car dashboards, TVs and flagship cell phones. The GPUs driving the smallest screens might have only one core, whereas the large screens require large multi-core GPUs with a beefy memory system.

Problem 2) Cache coherency

In our GPUs there are typically several shader cores, each with a L1 cache. These shader cores are connected to a shared L2 cache within the GPU. The GPU and the CPU cluster in the system is finally often also talking to a system level cache.

Problem 3) Address translation

Address translation is typically needed for every read and write transaction within the shader cores. Low latency as well as throughput that scales linearly with the number of cores is important. This is hard to achieve by directly wiring up the cores to a central Memory Management Unit.


In this role you will be responsible for Architecting the memory system found in the Mali and Immortalis GPUs.


The compute workload changes over time and there is an every increasing demand for more compute power. These are a couple of the mechanisms driving new features and improvements into our GPUs.


Architects have an overall responsibility of the architecture of the memory system. High level feature and PPA improvement requirements will be provided. The mission is then to explore the design space and discuss ideas with the rest of the team. As a part of this work you will document ideas and provide estimates of throughput, performance, energy consumption area and bandwidth for the proposed changes.


You will work closely with memory system designers and verification engineers and together we will deliver new memory systems to our GPUs that both meets our high quality standards as well as PPA targets.


Architects also work with the wider GPU team including project leads, architects for other parts of the GPU, the implementation team, our GPU modelling team and the software and firmware team to name a few.
