Abstract
A system for synchronizing central processing units (CPU) includes a schedule module that communicates a synchronization point, a first CPU that writes a first memory address to a first register in response to the first CPU reaching the synchronization point, and a second CPU that writes a second memory address to a second register in response to the second CPU reaching the synchronization point. The system further includes a first logical AND module that writes a first value to a third register based on the first and second memory addresses and a second logical AND module that writes a second value to a fourth register based on the first and second memory addresses. The system also includes a scheduler module that selectively generates a processor sync signal based on the first and second value.
