After we generate the parity bits we have the channel modulation part.
In other words, decoder I receives the message bits and the corresponding parity bits (generated by the encoder I) and generates an extrinsic information about the systematic bits.
The generated Y is corrected with the transmitted parity bits
through channel decoding.
The Beast FIFOs provides the ability to add extra parity bits
or additional control information bits to be buffered with the data bits.
By arranging 12 optical fibers in parallel, the 800 Mbit/s optical interconnect simultaneously transmits signals and parity bits
as well as standard 8-bit parallel data to implement a highly reliable transmission.
Cypress' new dual-ports are the only high-density, synchronous devices to offer x9 and x18 word widths so users can implement parity bits
for error-checking protocols.
The device's user-selectable parity bits
can be used to monitor the contents of program memory for error conditions, allowing the system's software to act on the error.
