I am using linux on a MPC5200 board.
There is a serial interrupt in the code. On accessing a global floating point variable from inside the interrupts I am corrupting variables elsewhere. Is accessing float variables inside not recommended and why ?

I am trying to complete a design started by my RF engineer, who to show his unhappiness with the management revealed little about the project.
I am not an rf engineer though i know some analog electronics.
his power amplifier was something like the attachment,
can someone help me complete it...
