Overview

The NOEL3 is a configurable RISC-V processor IP core, described in VHDL. The architecture is designed to utilize a small area footprint and to maintain execution predictability.

Key features

  • 32-bit RISC-V processor – with configurable extensions
    • RV32I: integer essential instructions
    • M: integer multiplication and division
    • A: atomic instructions for concurrency
    • F: single-precision floating-point arithmetic
    • C: compressed instructions to reduce code size
    • B: bit manipulation instructions
    • Zfh: half-precision floating-point operations.
    • Zfa: additional floating-point instructions
    • Debug module
  • Deterministic execution time guaranteed by barrel processor architecture
  • Configurable number of hardware execution threads (2 to 7)
  • One thread is always reserved for SoC operations
  • Utilizes tightly coupled memories instead of caches for predictable memory access
  • RISC-V PLIC interrupt controller
  • Support of AMBA AHB and APB-like deterministic bus for external memory and peripherals
  • Companion IP cores for bus fabrics, peripherals, networking and security (GRLIB IP Library)
