for (size_t i = 0; i < length; ++i) {
data[i] = data[i] >> 4; // Shift right by 4 bits for 12-bit data
}
}Step 2: Bit Manipulation
Bit handling is a all-important part of the 12 16 Simplified algorithm. It involves using bitwise operations to perform arithmetic tasks expeditiously. Here's an example of how to perform bit manipulation:
int16_t bitManipulation(int16_t a, int16_t b) {

return a + b;
}
int16_t subtract(int16_t a, int16_t b) {
return a - b;
}
int16_t multiply(int16_t a, int16_t b) {
return (a * b) >> 4; // Shift right by 4 bits for 12-bit multiplication
}
int16_t divide(int16_t a, int16_t b) {
return (a << 4) / b; // Shift left by 4 bits for 12-bit division
}Step 4: Output Scaling
Output scaling is the final step in the 12 16 Simplified algorithm. This step adjusts the output datum to the hope format and range. Here's how you can scale the output datum:
void scaleOutput(int16_t* data, size_t length) {
for (size_t i = 0; i < length; ++i) {
data[i] = data[i] << 4; // Shift left by 4 bits for 12-bit data
}
}Note: The bit shifts in the normalization and scale steps are specific to 12 bit datum. For 16 bit information, you may postulate to adjust the shift values consequently.
