[ASN.1] PER encoding

[Murali]

Hi All,

I am having doubts on PER encoding. Please help in clearing the issues.
 

Encoding of Normally small non negative whole number

10.6.2 lause of X691 says that "if n >= 64 .....". But what is the maximum value it can take? If it is less than or equal to 255, why do we need to appended a length?
 

I believe that only negative number has to be 2's complemented. Please tell me yes or no.

 

Encoding of a constrained whole number

In aligned variant,
if 2<= range <=255, the number is encoded in upper bound(log₂range) bits.
Consider, the range (1..8). 4 bits are needed for the representation. If the number to be encoded is 1, its equivalent encoding is 0001. Please let me know what I have interpreted is right?
 

I will keep posting encoding queries. Kindly clarify those doubts.

Thanks a lot.

regards,
Murali.
