Detailed Description

To generate the random numbers, the linear congruetial method is used. 2^32 is used as modulus. The overflow in the implementation is intended (and controlled, as UWORD32 is used as datatype which always is 32 bits wide).

Constructor & Destructor Documentation

PseudoRandomSource()

PseudoRandomSource::PseudoRandomSource ( UWORD32  s )

inline

construct a PseudoRandomSource object

Parameters

s

the seed

Member Function Documentation

getValue()

UWORD32 PseudoRandomSource::getValue

(

UWORD32

n

)

get a pseudo-random value from {0,...,n-1}

Parameters

n	the range of the random value to be returned

Returns

a number >= 0 and <= n - 1

After calling getValue, the next getValue call will use the next state of the random number generator (analogous to the C rand() function)
