Data-backup can push your costs up by 200%, and even there are high chances of data loss. Manage erasures and optimize your data recovery costs with an IP based on Reed-Solomon codes. Data erasure is a powerful way to tighten data security. Modern applications built for data centers and the cloud can make your organization vulnerable as storage devices have a high probability of being corrupted. While data-backup solutions are useful, they can push the costs up exuberantly. Why not get a smart solution that ensures 100% data recovery in case of up to certain storage device failures?

  • Parallel read of symbols a single clock across storage devices and fix erasures
  • Provides maximum correction capability by adapting the algorithm to correct only the erasures
  • Flow-through design with low latency
  • Zero additional memory for encoder design 

The Ethernet controller is compliant with IEEE802.3 and it provides an interface between the host subsystem and the Media Independent Interface (MII). The 10/100 Ethernet MAC consists of DMA (TX DMA, RX DMA), TLI (TX buffer, RX buffer), 10/100 Ethernet controller. The DMA automates data transfers and frees the CPU from this task. The Transaction Layer Interface (TLI) is a 64-bit wide block designed to provide a bridge between the DMA controller and a 10/100 Ethernet controller. The TLI uses 4 Kbytes FIFO for transmit (TX Buffer) and 2 Kbytes FIFO for receive (RX Buffer)

The memory 2 memory DMA controller transfers data from one memory location to another memory location. DMA operation begins when software enables a DMA, after setting the source and destination starting addresses, transfer count, and control information. The DMA engine moves the data block, and the DMA operation ends naturally when the number of bytes specified by the transfer count has been moved
