Time taken for computation - Poorva Bhargava - Jan 5 5:26:00 2001

Hello all,

Will you pls tell me how the time taken to calculate
an algorithum like fft can be computed using
TMS320C542 Dskplus Starter Kit.

Why using the algrebraic instruction B=T * #2h
ie. B= accumalator
T = temprory register
multiplied by a constant gives an errorneous
result.... i.e twice the actual answer

Thnaks and regards

Poorva __________________________________________________
