This function returns a 32-bit result of the
multiplication of a 16-bit variable var1 with
a 16-bit variable var2, with one shift left.
This function returns a 32-bit result of the
multiplication of a 16-bit variable var1 with
a 16-bit variable var2, with one shift left.
This function multiplies the 16-bit variable
var1 by the 16-bit variable var2 and shifts
the result left by 1. This 32-bit result is
added to the 32-bit variable var3 with sat-
uration and returns the 32-bit result.
This function multiplies the 16-bit variable
var1 by the 16-bit variable var2 and shifts
the result left by 1. This 32-bit result is
added to the 32 bit variable var3 with sat-
uration and returns the 32-bit result.
This function multiplies the 16-bit variable
var1 by the 16-bit variable var2 and shifts
the result left by 1. This 32-bit result is sub-
tracted by the 32-bit variable var3 with
saturation and returns the 32-bit result.
This function multiplies the 16-bit variable
var1 by the 16-bit variable var2 and shifts
the result left by 1. This 32-bit result is sub-
tracted by the 32-bit variable var3 with
saturation and returns the 32-bit result.
The lower 16 bits of the variable var1 is
multiplied with the lower 16 bits of the vari-
able var2. The higher 16 bits of the
variable var1 is multiplied with the higher
16 bits of variable var2, and the two 32-bit
results are added to the variable var3,
which is the return value.
