+# XH-1 Research
+
+Research repository for the **XH-1**, a custom **128-core RISC-V processor** and the first processor in the XH-series.
+
+This repository contains the research, experiments, architectural investigations, design decisions, prototypes, simulations, benchmarks, and technical notes produced during the development of XH-1.
+
+The purpose of this repository is to capture the **research and development process behind the processor**, including ideas that may ultimately be implemented, ideas that are rejected, experimental results, and questions that remain unresolved.
+
+This is intentionally separate from the main XH-1 documentation. The main documentation describes the processor's current architecture and implementation, while this repository records the research that leads to those decisions.
+
+---
+
+## About XH-1
+
+**XH-1** is the first processor in the XH-series and is designed around a **128-core RISC-V architecture**.
+
+The project explores the design of a high-core-count processor, including:
+
+- RISC-V ISA implementation
+- CPU core architecture
+- 128-core organization
+- Multicore scalability
+- Cache architecture
+- Memory hierarchy
+- Cache coherency
+- Interconnect design
+- Inter-core communication
+- Synchronization
+- Branch prediction
+- Verification
+- Simulation
+- Performance
+- FPGA implementation
+- ASIC considerations
+- Software and firmware
+
+XH-1 is currently in the research and development phase. Architectural decisions may therefore change as new research and experimental results become available.
+
+---
+
+# Purpose of This Repository
+
+The primary purpose of this repository is to answer:
+
+> **Why is XH-1 designed the way it is?**
+
+The main XH-1 documentation should describe what the processor currently does.
+
+This repository describes:
+
+- Why a particular architecture was considered
+- What alternatives were investigated
+- What experiments were performed
+- What results were obtained
+- Why particular designs were selected
+- Why other designs were rejected
+- What problems remain unsolved
+- What ideas may be explored in the future
+
+Research should be preserved even when an experiment does not produce the desired result.
+
+Failed approaches are valuable because they prevent the same mistakes from being repeated and provide useful information for future XH-series processors.
