IAR Embedded Workbench at a Glance


IAR Embedded Workbench for SuperH


Code Density

We took some real customerapplications and tested for sizewith HEW and with IAREmbedded Workbench.

Then we tested speed withCoreMark benchmark suite.

In the box you can see the results.

After all, it’s not knowing how the instruction set is implemented in silicon that counts, it’s knowing how to get there from the lines of C or C++ you write in the shortest and fastest way.

That is what we have been doing for more than 25 years.

SuperH tool benchmark

This is a code size test on real customer applications where the size of linked code + constants has been compared.

The test was performed with the following tools:

IAR EWSH v2.10Options used:-e -Ohz --double=32 --code_model=medium --data_model=medium --core=sh2afpu --dlib_config=dlib_defaults.h

Renesas HEW SH v9.3 Compiler options used:-cpu=sh2afpu, -debug, -speed, -goptimize, -gbr=auto, -chgincpath, -errorpath, -global_volatile=0, -opt_range=all, -infinite_loop=0, -del_vacant_loop=0, -struct_alloc=1, -lang=c, -nologoLinker options used:-optimize=branch (Run failed with -optimize=speed)
