Track 2 in the morning: 9:00 a.m. – 12:30 p.m. CEST

09:00 a.m.: A RISC-V in 1000 Lines of VHDL

Structure of the intended talk:

  • Short introduction of the speaker
  • What is RISC-V?
    • Market environment of the RISC-V.
    • Licensing of the RISC-V ISA – in relation to ARM
    • Core Instruction Set and optional Extensions.
  • How to implement a CPU in the classic way
    • Classic CPU design with separated datapath and controller.
  • Implementing a CPU as a FSMD (FSM with an implicit datapath)
    • Outline of the FSMD concept.
  • Comparison of the two concepts
    • Optimization possibilities in the datapath and the controller. Focusing on resource sharing of manual implementations and resulting area reductions.
    • Flexibility for future extensions and adaptions.
    • Strength of the FSMD concept in terms of code length.
    • Readability and easy understanding of a FSMD implementation. This is the main target of this implementation.
    • Easy and fast debugging due to little code length.
  • Concept of my implementation
    • A complete CPU within two VHDL processes. One register process and one combinatorically process.
    • Complete register set as a record type.
    • Basic resources of this CPU implementation and actions during instruction processing.
  • § Address progression
  • § Status flags and their administration
  • § Memory
  • § Register set
    • Usage of special FPGA resources (Block RAM) and its integration into the FSMD concept.
  • Explanation of the instruction set implementation in my design based on some instructions.
    • ADD: A very simple register-based instruction which is very common.
    • LOAD/STORE: Accessing external memory via the Avalon-Memory-Mapped-Bus.
    • JAL/JALR: Jump with link register. Frequently used for function calls.
    • A more complex instruction.
  • Comparison of the synthesis results with common implementations
    • Further comparison of my design before and after optimizations with respect to chip area and maximum clock frequency.
  • Verification methods used to verify my design.
  • How to get access to my design.

 

FPGA-Conference Europe – Digital Conference

FPGAs have made a regular evolutional leap forward in terms of new approaches and solutions for both hardware- and software developers.

The FPGA-Conference Europe, organized by ELEKTRONIKPRAXIS and the FPGA training center PLC2, is addressing that progress across all major manufacturers. It focusses on user-oriented, practically applicable solutions  that developers can quickly integrate into their own everyday work.

Take advantage of the combined knowledge of top-class FPGA experts!

*Important note: The conference will be presented through a purely web-based platform. Participation does not require any installation of a video conferencing application.
