Embedded systems are constantly becoming more complex, as they are increasingly equipped with more functionality. Networking capability is one of the most desired features even for embedded systems, hence network applications, typically used in desktop systems, are required to become available in the embedded system domain. Rewriting these applications to fit into embedded root file systems takes...
Increasing hardware capabilities and application requirements in embedded systems demand additional software initialization and configuration during startup, which adversely affects system boot time. Fast boot is essential for consumer devices in automotive, medical and entertainment markets. This paper describes “system level” optimization of embedded software to achieve faster boot times. We select...
Optimizing compilers provide users with compiler options to maximize program performance. The selection of compiler options is important as the resulted performance can vary significantly. The best combination of compiler options is not only dependent on the program itself, but it also is highly related to the configuration of the system and the architecture of the processor that the program runs...
We present a practical approach to optimizing whole-system performance of throughput-constrained embedded devices. The proposed methodology relies on a combination of systematic profiling and system-level analysis techniques which leverage hardware, application and tools knowledge. On our target platform - the Intel XScale iXP425 processor, an initial performance assessment identified instruction...
