Not really. The OP is working with Microblaze, I am working with NIOS2. Both archs do not have any provision for atomic memory modification at all, so we need to implement it by some pure software tricks (i.e. special provisions in the general ISR entry code) or by implementing a dedicated custom instruction. -Michael _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
