List of top Digital Logic Questions on Computer Arithmetic asked in GATE CS

Let R1 and R2 be two 4-bit registers that store numbers in 2's complement form. For the operation R1 + R2, which one of the following values of R1 and R2 gives an arithmetic overflow?
Consider three floating point numbers \(A\), \(B\) and \(C\) stored in registers \(R_A\), \(R_B\) and \(R_C\), respectively as per IEEE-754 single precision floating point format. The 32-bit content stored in these registers (in hexadecimal form) are as follows. \(R_A = 0xC1400000\), \(R_B = 0x42100000\), \(R_C = 0x41400000\) Which one of the following is FALSE?
