Job Description:

SiFive is creating RISC-V based CPU IPs faster and cheaper than ever before by combining the best practices of rapid, iterative software design with the proven fidelity of hardware engineering.  We are seeking an experienced leader in helping SiFive to research and develop next generation high performance processors.

Responsibilities:

• Lead a team of performance engineers to research, model and develop architecture  / micro-architecture ideas to build state-of-the-art performance processors that reach our aggressive performance targets.  

• Work with Product Management, Product Architect to define architecture / product performance target

• Design and carry out experiments to research and develop architecture / micro-architecture features 

• Work with the design team to implement and deliver performance target in RTL

Requirements:

• MS or PhD in Computer Science / Computer Architecture

• 10+ years of experience in high performance processor development

• 5+ years involved in the engineering team to deliver HW or SW products.

• Hands-on expertise with either HW development (RTL/implementation flows, verification/validation, backend flows, FPGA flows); FPGA debug, including the use of Integrated Logic Analyzer for waveform capture and debug

• Expert in analyzing performance bottlenecks in micro-architecture and software stack.  Awareness of potential security holes is a plus.

• Strong foundation in computer architecture of high performance out-of-order CPU designs.  Awareness of known industry micro-architectures is a plus.

• Strong foundation in workload characterization to identify HW/SW performance bottlenecks

• Strong foundation in workload reduction techniques for efficient performance simulation and projection
