port. After some number of clock cycles determined by the slave memory
latency and arbitration delay, valid readdata returns to the master port.
(See section
Data Computation
For write operations to dereferenced pointers, data-computation logic in
the accelerator computes the value of the expression to write to memory.
This value is the write-data for an Avalon-MM master transfer to
memory. Data-computation logic operates in parallel with the address-
computation logic.
Consider the pointer dereference in the following code which performs a
write operation:
*(ptr_to_int + i) = x + y;
Figure 3–10
