Description

The MESI InterSection Controller (ISC) is a coherence system controller. It supports the MESI coherence protocol for a cache data consistency. It synchronizes the memory requests of the system masters. It enables to keep the consistency of the data in the memory and in the local caches. This project provides the following elements:

  1. A synthesizable controller core with a complete environment of verification, synthesis, and documentation.
  2. Instructions for integrating MESI_ISC to a system.
  3. A definition and requirements of the system masters.
For a detailed description see the

MESI_ISC Specification (ver 0.12)



Project status:
  • Documentation: On progress. Main chapters have written.
  • RTL: Done.
  • Verification: On progress. A basic test plan has done.
  • Synthesis: On progress. Initial synthesis has passed successfully.
