IAR Embedded Workbench for RISC-V now releasedTools for Risc-V
The sophisticated optimization technology of IAR Embedded Workbench for RX generates very compact and fast code.
For this benchmark we took real customer applications and tested for size. The benchmark compares the total size of linked code and constants between code from IAR Embedded Workbench, CC RX and GCC.
In total for the tested applications, IAR Embedded Workbench generated 27 % smaller code than CC RX and 27 % smaller code than GCC.
