sub

Subtraction of two 16-bit integer or fractional values, returning a 16-bit result.

Assumptions

OMR's SA bit was set to 1 at least three cycles before this code, that is, saturation on data ALU results enabled.

Prototype


  Word16 sub(Word16 src_dst, Word16 src2)

Example

short s1 = 0x4000;  /* 0.5   */

short s2 = 0xE000;  /* -0.25 */

short result;



result = sub(s1,s2);

// Expected value of result: 0x6000 = 0.75
