I would like to know the transistor count for a processor to calculate the
MTBF.

 

The Transistor Count of a processor could be found in the Reliability REport
for the specific Chip.

MTBF could than be calculated based on the process of the CHIP.

From Reliability Report:
Process Technology: 0.13um CMOS
Product P/N: ADSP-BF532S 
 
e.g. 
0.13um CMOS Life Test Data Summary      
Overall Sample Size 1618     
Qty. Fail 0     
Equivalent Device Hrs. @ 55 deg C) 162741768     
FIT Rate (60% CL, 55 deg C) 6     
MTTF (60% CL, 55 deg C) 177609456     
FIT Rate (90% CL, 55 deg C) 14     
MTTF (90% CL, 55 deg C) 70678008     
Calculations assumes 0.7 eV Activation Energy
