3.3 Summary

In this chapter, we looked at eCos exception handling. We saw how the VSR table is used by eCos to run exception handling routines. We looked at the two options for exception handling. One option allows the HAL and kernel to provide default exception routines. The other option requires complete support of exception handling to be provided by the application.

Then we proceeded to examine the eCos split interrupt processing scheme using ISRs and DSRs. This provides us with a mechanism to reduce interrupt latency and allows interrupts to synchronize with the threads running in the system. Finally, we went through the eCos interrupt handling process.
