Embedded CPU Engineer, Platform Architecture
We are seeking a highly motivated and innovative Embedded CPU Engineer to join the Platform Architecture team. In this role, you will drive performance and efficiency optimization and architectural feature exploration for Apple's embedded CPUs that power critical functions across Apple's product line.
Description
As an Embedded CPU Engineer, you will help define CPUs that are specifically designed for running embedded applications across iPhone, iPad, Mac, and other Apple products. Your focus will be on understanding the unique constraints and opportunities of varied embedded use cases and translating those insights into improvements for both the software stack as well as the hardware including the CPU and its surrounding subsystem.
You will be responsible for deep-dive performance analysis of embedded workloads, identifying bottlenecks in existing microarchitectures, and proposing optimization strategies that balance performance, power efficiency, and area. Working closely with algorithm teams, software engineers, and CPU designers, you will explore ISA extensions, microarchitecture enhancements, and system-level optimizations tailored to embedded use cases.
This role requires some background in software profiling, performance modeling, and simulation environments. You will use and develop analysis tools and infrastructure to enable data-driven architectural decisions, create and analyze both real workloads and benchmarks representative of embedded workloads, and iterate with design teams to ensure ideas are implementable within power, timing, and area constraints.","responsibilities":"Analyze performance characteristics of embedded workloads including real-time processing, audio DSP, always-on scenarios, and embedded ML inference
