Modern network processors are also equipped with low-latency high-throughput on-chip interconnection networks optimized for the exchange of small messages among cores ( few data words ).

As a 3838 / 1553B data word, the HS action word is preceded by the 3 bit-time data word sync field and followed by the single bit parity bit.

The last 5 bits indicate the number of words to expect take a value of 1, which is matched by the single Data Word ( value 0x2 ) after the Status Word.
45.
When the data word is divided into 8-bit blocks, as in the example above, two 8-bit sums result and are combined into a 16-bit Fletcher checksum.
46.
An ordering problem that is easy to envision occurs when the data word is transferred byte-by-byte between a little-endian system and the Fletcher-32 checksum is computed.
47.
Memory was built in stacks of 29 planes of 4, 096 cores : 25 for the data word, two for " modulo-3 check " bits, and two for spares.
48.
A "'barrel shifter "'is a digital circuit that can data word by a specified number of bits without the use of any sequential logic, only pure combinatorial logic.
49.
The inputs to the ALU are the data words to be operated on ( called operands ), status information from previous operations, and a code from the control unit indicating which operation to perform.
50.
As an example, the data may be a message to be transmitted consisting of 136 characters, each stored as an 8-bit byte, making a data word of 1088 bits in total.
