Timing Analysis of Body Area Network Applications
Body area network (BAN) applications have stringent
timing requirements. The timing behavior of a BAN application
is determined not only by the software complexity,
inputs, and architecture, but also by the timing behavior
of the peripherals. This paper presents systematic timing
analysis of such applications, deployed for health-care
monitoring of patients staying at home. This monitoring
is used to achieve prompt notification of the hospital when
a patient shows abnormal vital signs. Due to the safetycritical
nature of these applications,worst-case execution
time (WCET) analysis is extremely important

A Framework to Model Branch Prediction for Worst Case Execution Time Analysis
Estimating the Worst Case Execution Time (WCET) of a program on a given hardware platform is useful in the design of embedded real-time systems. These systems communicate with the external environment in a timely fashion, and thus impose constraints on the execution time of programs. Estimating the WCET of a program ensures that these constraints are met. WCET analysis schemes typically model micro-architectural features in modern processors, such as pipeline and caches, to obtain tight estimates. In this paper
