Import!nt Notes5

1. DSPLin.5 "t proides a 'eneric &!" that abstracts the characteristics of the ph*sical lin

connectin' +!! and D! from the applications.

2. CMEM5 ()E) is an &!" and librar* for mana'in' one or more blocs of ph*sicall*conti'uous memor*.This ph*sicall* conti'uous memor* is useful as data buffers that ,ill beshared ,ith another processor :e.'. for the D! on an )&!3;.

3. Rin"IO5(ircular rin' buffer based data streamin'.

This ,ill hae definitions for interfaces and structures for Rin'" module.The Rin'" component proides data streamin' bet,een +!! and D! usin' a rin' buffer as

the transport.

"n a multiprocessor s*stem hain' shared access to a memor* re'ion an efficient mode of

data transfer can be implemented ,hich uses a rin' buffer created ,ithin the shared memor*.

The reader and ,riter of the rin' buffer can be on different processors.
