device:-


The instruction_master must be connected to the Nios® II processor's instruction code, that is, the ROM (Read Only Memory) that contains the Nios® II processor's software code.
Also, if you copy software code from ROM to random access memory (RAM) and run it from RAM, you also need to connect to the destination RAM.

■ Typical components that connect with instruction_master:

• Generic Tri-State Controller
• Legacy EPCS/EPCQx1 Flash Controller
• Serial Flash Controller
• Serial Flash Controller II
• Altera On-Chip Flash (MAX 10 only)
• On-chip memory
• SDRAM Controller
• DDR-SDRAM Controller
• DDR2-SDRAM Controller
• DDR3-SDRAM Controller

Such

data_master connects to the Slave component, which plays the role of storing and transferring general data other than the Nios® II processor instruction code and register settings necessary for controlling the Slave component. .

■ Typical components that connect with data_master:

• PIOs
• JTAG UART
• UARTs
• Components of (1) above (when used as data memory)
