Less is more.
aiPop for C16x/ST10 was developed to reduce the code size and/or to speed up the execution of assembly files for the C16x/ST10 processor families.

Why do you need aiPop for C16x/ST10?
The
size of compiled C code is becoming increasingly critical in embedded
systems, where the economic incentives to reduce ROM sizes are very
compelling.
Tests of aiPop for C16x/ST10 on complete reference customer applications showed overall code size reductions of more than 20%. Compacting code by 20% allows 25% more functionality to be packed into a flash memory of the same size.
Reduction of code size directly translates into reduced memory requirements and reduced hardware costs.
As opposed to file compression (zipping), the post-pass optimizations do not change the functionality of your system.
aiPop for C16x/ST10 supports incremental program verification, which is especially important for safety-critical applications.
Tedious and error-prone hand-crafted optimization is a thing of the past. With aiPop for C16x/ST10, you can easily select from and combine dozens of optimization techniques, trade size for speed and vice versa. Thus, saving considerable effort and expense.
aiPop for C16x/ST10 can be easily integrated into established tool-chains. It was designed and implemented after conducting in-depth studies of customer requirements and in close dialog with major developers of embedded applications such as Siemens ICM. Since 2000, aiPop-compacted software runs in millions of mobile phones worldwide. |

Availability
aiPop for C16x/ST10 supports all 16-bit C16x/XC16x/C16x2 and ST10/Super10 microcontrollers from Infineon Technologies and ST Microelectronics. It optimizes assembly files in .src format as produced by the TASKING C compiler. Optimization of hand-written code is supported to some extent provided that it is similar to compiler-generated code. aiPop for C16x/ST10 is available for Linux, Solaris and Windows 98/2000/NT/XP. |
