**Review Summary**

The document provides a solid overview of memory bandwidth considerations for the 128‑core XH‑1, covering definitions, RISC‑V context, scalability challenges, and implementation alternatives. It clearly identifies proposals, assumptions, and open questions. The quantitative analysis is sound, and the recommendations are reasonable.

**Key Issue Identified**

- **Citation Error (Reference [2])**: The RISC‑V Unprivileged ISA specification is cited with the version “20211203”, which is incorrect. The ratified version of the Unprivileged ISA is “20191213”. (The Privileged ISA version is correctly cited as 20211203.) This is a factual error in the supporting references.

No other material errors, unsupported claims, or contradictions were found. The document is technically credible for its research stage.
