 MODIFICATION HISTORY:

 Ver   Who  Date     Changes
 ----- ---- -------- -----------------------------------------------
 1.00a wgr  02/28/07 Added cache handling macros.

Define Documentation

#define XENV_MEM_COPY (  DestPtr, SrcPtr, Bytes   )     memcpy((void *) DestPtr, (const void *) SrcPtr, (size_t) Bytes)

Copies a non-overlapping block of memory. Parameters: DestPtr  Destination address to copy data to. SrcPtr  Source address to copy data from. Bytes  Number of bytes to copy. Returns: None. Note: The use of XENV_MEM_COPY is deprecated. Use memcpy() instead. This implemention MAY BREAK work if source and target memory area are overlapping.

#define XENV_MEM_FILL (  DestPtr, Data, Bytes   )     memset((void *) DestPtr, (int) Data, (size_t) Bytes)

Fills an area of memory with constant data. Parameters: DestPtr  Destination address to copy data to. Data  Value to set. Bytes  Number of bytes to copy. Returns: None. Note: The use of XENV_MEM_FILL is deprecated. Use memset() instead.

#define XENV_TIME_STAMP_DELTA_MS (  Stamp1Ptr, Stamp2Ptr   )     (0)

This macro is not yet implemented and always returns 0. Parameters: Stamp1Ptr  is the first sampled time stamp. Stamp2Ptr  is the second sampled time stamp. Returns: 0 Note: This macro must be implemented by the user.

#define XENV_TIME_STAMP_DELTA_US (  Stamp1Ptr, Stamp2Ptr   )     (0)

This macro is not yet implemented and always returns 0. Parameters: Stamp1Ptr  is the first sampled time stamp. Stamp2Ptr  is the second sampled time stamp. Returns: 0 Note: This macro must be implemented by the user.

#define XENV_TIME_STAMP_GET (  StampPtr   )

Time is derived from the 64 bit PPC timebase register Parameters: StampPtr  is the storage for the retrieved time stamp. Returns: None. Note: Signature: void XENV_TIME_STAMP_GET(XTIME_STAMP *StampPtr) This macro must be implemented by the user.

#define XENV_USLEEP (  delay   )

XENV_USLEEP(unsigned delay) Delay the specified number of microseconds. Not implemented without OS support. Parameters: delay  Number of microseconds to delay. Returns: None.
