Method Details

evaluateBinary

long evaluateBinary(int sizeout,
 int sizein,
 long unsignedIn1,
 long unsignedIn2)

Evaluate the binary operation using long data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed long value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

unsignedIn1 - unsigned input 1

unsignedIn2 - unsigned input 2

Returns:

operation result.

• Utils.bytesToLong(byte[], int, boolean)

evaluateBinary

BigInteger evaluateBinary(int sizeout,
 int sizein,
 BigInteger unsignedIn1,
 BigInteger unsignedIn2)

Evaluate the binary operation using BigInteger data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

unsignedIn1 - unsigned input 1

unsignedIn2 - unsigned input 2

Returns:

operation result.
