SATA Port Multiplier with Sandbox IP Core

The IntelliProp IPP-SA128A-PM SATA Port Multiplier with Sandbox IP Core is a production-hardened, high-efficiency storage routing solution engineered to connect a single SATA host port to multiple discrete SATA target devices. Operating entirely within the hardware logic fabric, this core combines standard port multiplier capabilities with a dedicated, isolated hardware “Sandbox” area designed for real-time inline data processing.

Implementing custom security rules, hardware-enforced deep packet inspection, or proprietary sector-level data alterations usually requires complex external bridging chips that degrade latency. The IPP-SA128A-PM solves this by providing an accessible, secure logic boundary directly inside the data path. This allows engineers to drop their proprietary IP or custom algorithms directly into the active storage stream, executing complex logic at deterministic, line-rate speeds with near-zero latency.

Fully compliant with industry-standard Serial ATA specifications, the IPP-SA128A-PM automates port routing, command distribution, and interface state management completely in hardware. Its clean, fully synchronous RTL architecture is optimized for predictable timing closure, making it an ideal choice for secure defense architectures, cryptographic storage drives, and mission-critical data isolation platforms.

Features

• FIS-Based Port Multiplexing: High-performance hardware logic supporting Frame Information Structure (FIS) based switching to route data paths to multiple targets simultaneously.
• Isolated Hardware Sandbox: Features a dedicated internal logic boundary inside the core data path for seamless integration of custom or proprietary engineering algorithms.
• Deterministic Throughput: Maintains full line-rate serial storage speeds across the multiplexer fabric with sub-microsecond propagation delay.
• Zero Host CPU Burden: Command sorting, target routing, and response aggregation are managed entirely in hardware logic with no software overhead.
• Inline Customization Gateway: Ideally suited for integrating custom hardware-level encryption (AES), real-time command filtering, or advanced telemetry monitoring.
• Clean Protocol Isolation: Employs independent clock-domain crossings and deep internal buffering to safely isolate host signaling from downstream target faults.
• Full Speed Interface Support: Native hardware alignment fully compliant with standard SATA Gen-1, Gen-2, and high-speed Gen-3 link rates.
• Flexible PHY Integration: Integrates smoothly with a wide variety of industry-standard transceiver layers across leading FPGA and ASIC target fabrics.
