Code transformation strategies for extensible embedded processors
Embedded application requirements, including high performance, low power consumption and fast time to market, are uncommon in the broader domain of general purpose applications. In order to satisfy these demands, chip manufacturers often provide developers with the possibility to define application-specific Instruction Set Extensions (ISEs). Many techniques have been proposed that automatically identify the most beneficial ISEs from source code, so that compilers can identify the ‘best’ instruction set for the underlying machine. However, can we simply retrofit these techniques into a traditional compiler, or does ISE identification demand different tuning of the heuristics utilized throughout the optimization pipeline? In this paper, we show why compilers should sometimes make different decisions when targeting customized processors, and we show how traditional ISE identification techniques can improve significantly if the code is properly transformed in order to expose ...
