Hi,
I want to know how to calculate the processor timing values? ie to know how much timing is taken to execute each instructions? How to calculate this? How to calculate the latency period?
Regards,
Priya.
adc negative number binnary
I did it like this. Is it correct? 2^24 = 16777216. I want my weight in kg with resolution of 0.1. So divided 16777216/1500 = 11184 (2BB0). 2BB0 when represented in fractional form gives 0.001333237.
I calculate how many 0.001333237 are in the obtained result. The...
lsb msb 2s complement
As the last 2 bits are always 0, should I take the 24 bits (ie considering last 2 bits as zero) and map into weight or should I take the first 22 bits alone(discarding the last 2 bits and treating as 22 bit value) and map into weight.
converting back 2s complement
I am using Atmels 89C51 microcontroller. Why it is necessary to convert into 2's complement form. Already the result is in the 2's complement form. Before I had dealt with ADUC816. The 16-bit result would be available in the data register in binary coding. Suppose...
adc 2s complement
I have CS5550 ADC from cirrus logic. The output register is of the form
-(2^0) (2^-1) (2^-2) .......... (2^-23)
This is a 24-bit register. It is given in the datasheet that : These register contain the last value of the measured results of AIN1 and AIN2. The results will...
