We are seeking a highly skilled and experienced Staff Research Scientist with strong ISA extensions experience. This is a high-level research and development role.
Key Responsibilities:
- Analyse dynamic language overhead: Profile V8 and ArkTS interpreter/JIT to identify operations that consume disproportionate cycles (type checks, inline cache misses, garbage collection barriers, dynamic dispatch, deoptimisation).
- Design ISA extensions: Propose new instructions or architectural features that accelerate common dynamic language patterns while maintaining backward compatibility and security boundaries.
- Prototype in software: Modify V8, ArkTS interpreter, or JIT compiler to use new instructions, measuring speedup on representative workloads (OpenHarmony apps, JavaScript benchmarks, browser workloads).
- Model in architectural simulators: Implement proposed extensions in GEM5.
- Collaborate on RTL implementation: Work with digital design teams to refine instruction encoding, pipeline integration, and verification requirements.
- Publish and patent: Document novel contributions through internal technical reports, conference papers, and patent applications.
Required:
- Deep understanding of CPU microarchitecture: pipelines, out-of-order execution, branch prediction, memory hierarchy, ISA design principles.
- Experience with architectural simulation (GEM5, Sniper, ZSim, or proprietary tools).
- Familiarity with interpreter or JIT compiler internals — any of: V8, SpiderMonkey, JavaScriptCore, HotSpot, ART, LuaJIT, PyPy, or similar.
- Strong C/C++ and systems programming skills.
