Honored ContributorNios ii Instruction Macros
Can anyone explain to me how macros of the nios ii instructions (addi, subi, movi, ...) are interpreted in computer system vhd file?
Do their entities and definitions exist in the vhd file of the whole nios ii system? Thanks in advance.13 Replies
Altera_ForumIs it true that the only possible way to customize the Nios ii processor is creating custom instructions? Is there any other way?

It depends on what you call customize. Outside the CPU you can also create components that implement a hardware acceleration. Altera has an example of this here (http://www.altera.com/support/examples/nios2/exm-checksum-acc.html).

Thank you for the provided link.
A meaning by saying customizing could be designing those MIPS' instructions that are not provided in the Nios ii processors' ALU...
