gDSPsim

The Gnu Digital Signal Processor Simulator is a useful tool for developers looking to test out C54x executables. In order to use this tool, users would need to compile binutils for the C54x and compile the test program within gDSPsim's test directory. While work is being done on the TMS320C55x, it still needs significant improvement before it is useful to non-developers.

In terms of requirements, users would need to have gtk 1.2 or higher and GtkExtra installed. To configure the tool for the C54x, users must input "./configure --target=c54x --prefix=/usr." Although "--prefix=/usr" is not required, the default value of /usr/local does not have the same path on many systems by default. After configuration, users must input "make" and "make install" to create binutils binaries with prefix names of c54x-. The important binutils binary is c54x-as, however, other binutils and man pages are also generated.

To compile test code, users would input "c54x-as -o test1.o test1.asm" and "c54x-ld test1.o -o test1.out." Overall, the Gnu Digital Signal Processor Simulator is a useful tool for developers looking to test out C54x executables, and is accessible through a straightforward installation process.
