<!-- of Alibaba’s T-Head Opene906 processor in PULP -->
Revision as of 20:05, 20 January 2022
- Type: Semester Thesis
- Professor: Prof. Dr. L. Benini
Alibaba has recently (October 2021) introduced a range of RISC-V processors with the Xuantie family ranging from the E902 micro-controller class core to the C910 core for servers in data centers. This also includes the XuanTie C906 core found in the Allwinner D1 single-core RISC-V processor. T-Head had open-sourced four RISC-V-based Xuantie series processor cores, namely Xuantie E902, E906, C906, and C910, as well as related software and tools .
PULPissimo is an open-source, single core RISC-V microcontroller  developed by PULP that hosts an industrial-grade processor, namely CV32E40P .
The goal of this project is to replace our in-house processor with T-Head’s Opene906:
- Study T-Head’s opene906 source code.
- For the latter, at IIS we have forked T-Head’s processors in our environment (Mentor Questa for RTL simulation and SW toolchain building)  to ease development/usage bring-up overhead.
- Integrate T-Head’s opene906 into PULPissimo to replace the existing processor developed by PULP, CV32E40P
- Verify basic functional correctness in simulation
- Synthesize the new processor, evaluate area and timing figures
- ASIC Backend flow towards PULPissimo SoC tapeout
- 15% Literature / architecture review
- 30% RTL implementation
- 30% Backend
- 25% Evaluation
- Experience with digital design in SystemVerilog as taught in VLSI I
- Must have visited VLSI II in a previous semester or take it alongside the thesis
