Notes LIFO

====== = = = LIFO (Last In First Out) = = = = ===========

DATA structures help >organize< embedded system control and >storage< of data.

LIFO Buffer :

Producer => Data Buffer ==> Consumer

Producer : Creates and packages data from sensors or connected devices

Data Buffer : data structure in shared memory implemended between two processing interfaces.

Consumer : Processes data to make decisions, control outputs or communicate externally

COMMANDS :

-> PUSH : to add data INTO the buffer
-> POP : to get out data FROM the buffer

LIFO : Adds and removes data items to/from the same end (created with a contigous block of memory like LINKED LIST)

=> referred to as a STACK => Similar to processor stack, but diferent
