16-bit multiply example
Consider an device with a 10-bit ADC
A, B ; 2 bytes
A, #0 ; 2 bytes
B, YL ; 3 bytes
– Basic filtering of data requires a 16-bit multiply operation
– 16-bit multiply operation is compared below
A, XL ; 2 bytes
B, YL ; 3 bytes
AB; 1 byte
R0, A; 1 byte
R1, B; 3 bytes
A, XL ; 2 bytes
B, YH ; 3 bytes
