- REVISION HISTORY
-
- Description: Created separate file for the shr function. Sync'ed up with
- the current template and fixed tabs.
-
- Description: 1. Modified code by seperating var2=0 condition.
- 2. Changed Input range definitions.
-
- Description: Made changes based on review meeting.
- 1. Changed Overflow definition.
- 2. Removed pseudo-code.
- 3. Deleted (var2>15&&var1!=0) condition.
- 4. Moved var2>0 condition in front of var2<0 condition.
-
- Description: Changed the function prototype to pass in a pointer to the
- overflow flag instead of using global data.
-
- Description: Made changes per formal review. Updated template.
- Removed code that updates MOPS counter.
- Changed parameter name from "overflow" and "pOverflow".
- Optimized code by eliminating unnecessary typecasting.
- Filled in the PSEUDO CODE section
-
- Description: Further optimized typecasting for overflow case

- FUNCTION NAME: shr
-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- var1 = 16 bit short signed integer (Word16) whose value falls in
- the range : 0xffff 8000 <= var1 <= 0x0000 7fff.
-
- var2 = 16 bit short signed integer (Word16) whose value falls in
- the range : 0xffff 8000 <= var2 <= 0x0000 7fff.
-
- pOverflow = pointer to overflow (Flag)
-
- Outputs:
- pOverflow -> 1 if the shift operation resulted in overflow
-
- Returns:
- product = Shifted result limited to 16 bits (Word16)
-
- Global Variables Used:
- None
-
- Local Variables Needed:
- None
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function arithmetically shifts the 16 bit input var1 right var2 positions
- with sign extension. If var2 is negative, arithmetically shift var1 left by
- -var2 with sign extension. Saturate the result in case of underflows or
- overflows.

- None
