IP REED SOLOMON IP CORE

Overview

Reed Solomon encoding and decoding IP core designed to provide protection for data storage
in space applications. Reed Solomon is a block code, the transmitted codeword is divided in block of data called symbols. Symbols are coded on several bits as elements of a Galois field. The Reed Solomon IP is based on the Galois field GL(2^4), symbols are coded on 4 bits and the maximum size of a message after encoding is 15 symbols (60 bits).

Key features

• 

  Configurable input data size

  Configurable ECC size

  1 or 2 symbol correction capacity, symbol size is a quarter of the ECC size

  Decoder indicates when a symbol is corrected

• 

  Decoder indicates when an incorrigible error is detected

  Encoder is a combinatory entity

  Configurable output delay for decoder

Line Up

Each 3D PLUS standard product and SiP solution are defined by a specific part number based on the part number decoder provided below. The ordering information consist as a minimum of the following 3 items for fully define a product:

• The product’s Part Number
• The temperature range
• The quality grade

For High Reliability products or SiPs for Aerospace applications, a Source Control Drawing (SCD#) referenced 3DPA-xxxx is available for each product. It shall be used for its procurement in addition to other ordering information.
