Software UART: A use case for VSCPU worst-case execution time analyzer
Yıldız, A.; İskender, Deniz; Özlü, G.; Uğurdağ, Hasan Fatih; Aktemur, Tankut Barış; Gören, S. (IEEE, 2019)This paper presents our early results of the development of a Worst-Case Execution Time (WCET) analyzer for VSCPU by implementing a software UART system. Our WCET analyzer takes a C program as input and gives the time taken ...
