ECC with BCH Algorithm IP Core

The IntelliProp IPC-BL119A-ZM ECC with BCH Algorithm IP Core is a production-hardened error correction module engineered to protect high-speed digital datapaths against randomly distributed bit errors. Utilizing industry-standard Bose-Chaudhuri-Hocquenghem (BCH) cyclic block codes, the core injects parity bits during encoding and performs high-speed syndrome calculations during decoding to guarantee data integrity in solid-state storage (NAND Flash, SATA, SAS), satellite communications, and wireless transmission systems.

Architected for maximum performance and low latency, the IPC-BL119A-ZM features fully parallelized encoding and decoding datapaths. The encoding process introduces zero additional latency, allowing data streams to pass through unhindered. The core is highly configurable, enabling engineering teams to tailor word lengths, block sizes, correction strength ($T$), and interface bus widths to meet exact system latency and throughput targets.

Delivered as clean, synchronous RTL, the core easily integrates with ONFI/Toggle Flash Controllers, memory bridges, and high-speed communication interfaces across leading FPGA fabrics and custom ASIC designs.

Features

• Standard BCH Error Correction: Implements industry-standard Bose-Chaudhuri-Hocquenghem (BCH) algorithms to detect and correct random bit errors across linear block structures.
• Zero-Latency Parallel Encoding: Highly parallelized encoder structure processes outgoing data streams without introducing pipeline latency delays.
• High-Throughput Parallel Decoding: Accelerated parallel decoder state machines rapidly perform syndrome generation and error location searches for ultra-low decode latency.
• Flexible Data Interface: Features configurable 32-bit, 64-bit, 128-bit, or 256-bit FIFO data interfaces to match host system bus architecture.
• Configurable Code Parameters: Supports user-definable code word lengths ($K$) up to 1024 bytes, configurable block sizes, and adjustable error correction thresholds ($T$).
• Scalable Block Engines: Fully configurable number of independent encode and decode blocks to scale throughput with system bandwidth requirements.
• Broad Target Application Support: Engineered for integration into SATA, SAS, and Flash storage controllers, satellite telemetry, optical/wireless communications, and xDSL modems.
• Synchronous Synthesizable RTL: Delivered as fully synchronous Verilog source code/netlist optimized for rapid placement, routing, and timing closure across modern FPGAs and ASICs.
