Question 8. With a bus clock at 80 MHz, the slowest we can run SysTick interrupts is80,000,000/16777216=4.768 Hz. How could we sample at 1 Hz (trigger ADC exactly every 1sec)?Give a flow chart including a mailbox used to pass data to the foreground.

Why is binary fixed-point faster than decimal fixed-point?

Digital Systems

What errors occur with these poorly written equations?

I=75-(N / 1024)

\mathbf{I}=\mathbf{N}-(75 / 1024)

Question 5. What error might occur with multiply? Prove this equation has no overflow(where N comes from a 12-bit ADC)

I=(160-N) / 4096

Digital Systems

Can the sum of two fixed-point numbers overflow? How does one detect overflow?
