void ckernel::addcmul_tile(uint32_t idst0, uint32_t idst1, uint32_t idst2, uint32_t odst, uint32_t value)

Performs elementwise addcmul (add with constant multiply) operation.

Mathematical formula: odst = idst0 + (value * idst1 * idst2)

This operation computes the elementwise result by:

1. Multiplying the scalar value with each element of idst1

2. Multiplying that result with the corresponding element of idst2

3. Adding the result to the corresponding element of idst0

Output overwrites odst in DST.

The DST register buffer must be in acquired state via acquire_dst call. This call is blocking and is only available on the compute engine.

Argument	Description	Type	Valid Range	Required
idst0	Index of the tile in DST register buffer (first input)	uint32_t	Must be less than the size of the DST register buffer	True
idst1	Index of the tile in DST register buffer (second input)	uint32_t	Must be less than the size of the DST register buffer	True
idst2	Index of the tile in DST register buffer (third input)	uint32_t	Must be less than the size of the DST register buffer	True
value	Scalar constant multiplier	uint32_t	Any valid value	True
odst	Index of the tile in DST register buffer (output)	uint32_t	Must be less than the size of the DST register buffer	True
