Efficiency Considerations
You can put your shared data on any processor. However, it is most efficient to put the data
on the processor that will use it most often, or that is performing the most time-critical
operations. (It takes slightly longer to access data on another processor than to access data
on the local processor.) If you wish, you can put some of your data on one processor and
other data on a different processor. You must be careful to keep track of which data items are
stored in which location.
32-bit and 64-bit operations operate slightly faster if the address is an exact multiple of four.
16-bit operations operate slightly faster if the address is an exact multiple of two.
Digital I/O
The digital I/O image- including input (1001-1512), output (1-512), and soft signals (2000-
2512 and 3001-3004)-is managed by processor 1. These signals are shared by all processors.
You can use the soft signals to pass control information between processors.
