commands. Maximum throughput for interprocessor data
transfer is 400M bytes/s over the external port. Broadcast writes
allow simultaneous transmission of data to all ADSP-21160Ns
and can be used to implement reflective semaphores.

Six link ports provide for a second method of multiprocessing
communications. Each link port can support communications to
another ADSP-21160N. Using the links, a large multiprocessor
system can be constructed in a 2D or 3D fashion. Systems can
use the link ports and cluster multiprocessing concurrently or
independently.
