Document Summary
C sc 230 computer architecture and assembly language. April 2000 exam sample solutions: (12 marks) circle the correct answer for each of the following: The 8-bit two"s complement representation of -1510 is 111100012. Two"s complement representation has different representations for +0 and 0. In two"s complement addition, overflow can only occur when adding two positive numbers. Single bit parity allows for the detection and correction of single bit errors. On the 6811, the external address and data buses are asynchronous. The data bus to main memory must have the same number of bits as the word size. A processor must have a stack pointer register in order to support a jump to subroutine instruction. Program memory parameter passing can never be used if the program code is to be stored in rom. On the 6811, on-processor memory can share addresses with off-processor. Unless explicitly forbidden by the user program, nested maskable interrupts are allowed on the 6811.
