  T1 is an open-source, research-oriented implementation of a RISC-V vector processor. It aims to explore the microarchitecture tradeoffs of the RISC-V vector extension (RVV) by providing a configurable and modular platform for experimentation. The project includes a synthesizable core written in SystemVerilog, a software toolchain, and a cycle-accurate simulator. T1 allows researchers to modify various parameters, such as vector register file size, number of functional units, and memory subsystem configuration, to evaluate their impact on performance and area. Its primary goal is to advance RISC-V vector processing research and foster collaboration within the community.

  The Chips Alliance T1 project details the implementation of a RISC-V vector processor, showcasing a practical application of the RISC-V vector extension. This implementation aims to serve as a concrete example and a learning platform for developers interested in understanding and utilizing RISC-V vector processing capabilities. The project provides a comprehensive overview of the processor's architecture, microarchitecture, and software ecosystem.

  The T1 processor implements the RISC-V Vector (RVV) instruction set architecture, allowing it to perform Single Instruction Multiple Data (SIMD) operations. This enables parallel processing of data elements, significantly boosting performance for computationally intensive tasks commonly found in areas like multimedia, scientific computing, and artificial intelligence. The architecture adheres to the established RISC-V principles of modularity and extensibility.

  The microarchitecture details reveal the inner workings of the T1 processor, explaining how the vector instructions are executed. This includes the organization of functional units, data paths, and control logic responsible for fetching, decoding, and executing vector instructions. The implementation likely addresses key microarchitectural considerations for vector processing, such as efficient data loading and storage, vector register file management, and handling of varying vector lengths.

  The project emphasizes a complete software ecosystem surrounding the T1 processor, recognizing that hardware is only part of the solution. This ecosystem likely includes tools for assembling and compiling code for the RVV ISA, simulators for testing and debugging, and potentially libraries optimized for vector operations. This complete software stack allows developers to write, compile, and run vectorized applications on the T1 processor or within a simulated environment. The availability of such a software ecosystem lowers the barrier to entry for developers and accelerates the adoption of RVV.

  Furthermore, the T1 project, by being open-source and providing detailed documentation, fosters collaboration and community involvement.
