Although a microprocessor can use interrupt service routines to capture and store data from each of the
inputs in turn, it takes many instruction cycles to achieve, which reduces the temporal accuracy.
Microsemi’s processor offload technology for analog I/O implemented in the SmartFusion™ family of
integrated devices, for example, can overcome this problem. At the same time, it can reduce the loading
on the host processor by massively reducing the number of interrupts it has to service, providing more
time to run complex signal-processing algorithms.
