Abstract
A microcontroller system may include a microcontroller having a processor and a first memory, a memory bus and a second memory in communication with the microcontroller via the memory bus. The first memory may include instructions for accessing a first data set from a contiguous memory block in the second memory. The first data set may include a first word having a first value and a plurality of first other words. The first memory may include instructions for receiving a write instruction including a second data set to be written to the contiguous memory block. The first memory may include instructions for determining whether the first value equals the second value. If so, the first memory may include instructions for writing the second data set to the contiguous memory block and updating the first value.
