In this paper, we investigate how the presence of a general purpose operating system influences the reliability of modern embedded Systems-on-Chips (SoCs). We experimentally study the difference in the neutron-induced error rate of SoCs when executing the application bare to the metal and on top of the Linux kernel. Our analysis demonstrates that Linux presence barely affects the Silent Data Corruption...
Abstract -- Nowadays major embedded systems functionalities are developed in software. Moreover, to attend the market exigencies the software productivity has to be improves. This work analyzes the overhead caused by the application of abstraction levels in embedded systems software development. This analysis was done based in Google Android. The obtained results showed that even about 80% of the...
Fueled by the exponential growth in transistors available to processor designers, cache memories became a very significant percentage of the overall area, power dissipation and energy consumption of modern systems. Instruction cache memories, however, typically hold highly redundant information in each of their columns, due to the repeated use of instructions and registers by compilers. Current memory...
