4. Introduction • This slides provides comprehensive information that will help you understand how to create a FPGA based SOPC system implementing on your FPGA development board and run software upon it.

5. Required Features (1/2) • The Nios II processor core is a soft-core central processing unit (CPU) that you could program onto an Altera field programmable gate array (FPGA). • This chapter illustrates you to the basic flow covering hardware creation and software building.

6. Required Features (2/2) • The example NIOS II standard hardware system provides the following necessary components: • Nios II processor core, that’s where the software will be executed. • On-chip memory to store and run the software. • JTAG link for communication between the host computer and target. • Hardware (typically using a USB-Blaster cable). • LED peripheral I/O (PIO), be used as indicators.
