13 © 2010 Renesas Electronics America Inc. All rights reserved. 13 Code Density We took some real customer applications and tested for size with HEW and with IAR Embedded Workbench. Then we tested speed with CoreMark 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. 14.3% smaller 7.9% faster
