64 bit integer support

Started by Unknown July 1, 2002
Hallo everyone.
Are 64bit integer math operations support in CW4.1 with DSP56F805?
If yes, how can I enable it ? I've tried with "#pragma longlong on" but it
seems not work.

Thanks
Marco

Sorry, but there is not 64 bit integer support that I know of, there isn't
even a 64 bit type supported by the compiler as the accumulators on the DSP
(where most of the math is done) are only 36 bits wide.

P.S. #pragma longlong is not supported by the DSP56800 tools. Please refer
to the Targeting_DSP56800 manual to see what #pragmas are supported.
