#define Pa_osalBeginMemAccess   Osal_paBeginMemAccess
 This macro is used to alert the application that the PA is going to access a block of memory. The application must ensure cache coherency for multi-core applications.
#define Pa_osalEndMemAccess   Osal_paEndMemAccess
 This macro is used to alert the application that the PA has completed access to a block of memory. If the memory block is cached then the application would need to ensure that the contents of the cache are updated immediately to the actual memory.
#define Pa_osalMtCsEnter   Osal_paMtCsEnter
 The macro is used by the PA LLD to provide critical section to protect its global and shared resources access from multiple cores. If the PALLD operates in single-core environment then these macros can be defined to be NOP.
#define Pa_osalMtCsExit   Osal_paMtCsExit
 The macro is used by the PA LLD to exit a critical section protected using the Osal_paMtCsEnter() API.

Detailed Description

This is the sample OS Adaptation layer which is used by the PA low level driver.

The OSAL layer can be ported in either of the following manners to a native OS:

Approach 1:
Use Prebuilt Libraries

Approach 2:
Rebuilt Library
