Hello everyone,

I have 10 floating point variables need to protect from power intensive and store them their latest value. ULP advisor recommends moving them to RAM.

How can i do this?

Thanks

Show the actual code that the advisor complains about.

So that variables are constant.

Remove 'const' modifier from their declaration and they will be moved to RAM.

Regards,

Peppe

Thanks for reply.

Variables aren't constant.

for example;

float k3 = 1.0;
float Q_SES;
static float Forecast_t, Forecast_t1;

Q_SES = Forecast_t1 * k3;

float k3 = 1.0;
float Q_SES;
static float Forecast_t, Forecast_t1;

Q_SES = Forecast_t1 * k3;
