Subject: interrupt overhead on ARM architecture
Date: Mon, 28 Jul 2008 19:23:04 -0700	[thread overview]
Message-ID: <488E7F08.7060309@manoweb.com> (raw)

Hi there, I was wondering if somebody ever did some measurements of the
interrupt overhead, measured in clock cycles. Basically how much time it
takes to do the context switch and reach the ISR, and back. My target is
the ARM9...

Thanks
Alessio
