Result was a non-zero value, a negative value, had a carry and extended bits. b. Trace mode was not on and was executed in supervisor mode. C. Any higher interrupt priorities higher than level 3 will be recognized.
An input I/O device has a polled status register and a data register. The status register is set to one to indicate that input data is ready. Using typical assembly-like code, write a polling routine that transfers each bye of input data to a processor register. If instructions are executed in 500 ns each, calculate the maximum rate at which data could be transferred over this interface.
Compilers have great impact on the computing performance. Assume that for a program Pro, compiler A in machine A results in 1E9 instructions (instruction count=1*), while compiler B in machine B results in 2E9 instructions (instruction count=2*). CPI_A= 1 and CPI_B=2. Which processor is faster and by how much, if clock cycle time of A is 1 ns, clock cycle time of B is 2ns?
