5. Accelerating Code Using
the Nios II Software Build
Tools Command Line
Creating an
Accelerator from
the Command
The Nios II software build tools support the Nios II C2H Compiler on the
command line with the nios2-c2h-generate-makefile command. This
command creates a C2H makefile fragment that specifies all accelerators
and accelerator options for an application.
Line
1
C2H Compiler projects created on the command line cannot be
imported into the Nios II Software Build Tools for Eclipse.
Altera recommends creating new C2H accelerators with the
Nios II IDE.
The nios2-c2h-generate-makefile command usage is as follows:
nios2-c2h-generate-makefile
--sopcinfo= <SOPC Builder System File> [OPTIONS]
1
This command creates a new c2h.mk each time it is called,
overwriting the existing c2h.mk .
Table 5–1 lists the command line arguments for the
nios2-c2h-generate-makefile command.
Table 5–1. nios2-c2h-generate-makefile Command Line Arguments (Part 1 of 2)
--sopcinfo
--app-dir
--accelerator
Argument Name
Meaning
The path to the SOPC Builder system file ( .sopcinfo ).
Directory to place the application Makefile and ELF. If
omitted, it defaults to the current directory.
Specifies a function to be accelerated. This argument
accepts up to four comma-separated values:
Target function name
Target function file
Link hardware accelerator instead of original
software. 1 or 0. Defaults to 1.
Flush data cache before each call. 1 or 0. Defaults
to 1.
Examples:
--accelerator=doDMA,../../DMA.c,1,0
--accelerator=analyze,../../finite.c
--enable_quartus
Building the application compiles the associated
Quartus II project. Defaults to 0.
