I am looking for a tool chain for a new custom micro-controller. The core has a very basic instruction set and doesn't have to be C- programmable. Still, the software is complicated enough, that we would like to have primitive debug capabilities at least.
Features needed:
-assembler
-linker(possibly)
-source code debugging
-single stepping
-register and memory content display
-breakpoints
-hardware debugging interface
-integratioin of simulator
Are there companies out there that specialize in creating these types of software solutions. The two companies that I have heard of so far are: retarget compilers and isystem. Any comments on these two companies?
