Introduction to the C2H Compiler
System Architecture
shows the architecture of a simple Nios II processor system
that includes one hardware accelerator.
Figure 1–1. Example System Topology with Single Hardware Accelerator
SOPC Builder automatically integrates the accelerator logic into the
system as an SOPC Builder component. If there is more than one
accelerator in the system, multiple accelerators appear in SOPC Builder.
Accelerators are separate from the Nios II processor but can access the
same memory devices that the Nios II processor can.
