Which of the following parts interprets program instructions and initiates control operations?
At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?
Which of the following is/are the advantages of using a control chart for inspection? (i) A control chart indicates whether the process is in control or out of control. (ii) A control chart determines process variability. (iii) A control chart ensures product quality. (iv) Scrap or percentage reduction can be reduced by taking the necessary actions in time against the warnings indicated by control charts. (v) Control charts build up the reputation of the organization through customer’s satisfaction. (vi) The control chart can detect the unusual variations taking place in a process.
Consider the following code sequence having five instructions I1 to I5. Each of these instructions has the following format. OP Ri, Rj, Rk Where operation OP is performed on contents of registers Rj and Rk and the result is stored in register Ri I1: ADD R1, R2, R3 I2: MUL R7, R1, R3 I3: SUB R4, R1, R5 I4: ADD R3, R2, R4 I5: MUL R7, R8, R9 Consider the following three statements. S1: There is an anti-dependence between instructions I2 and I5 S2: There is an anti-dependence between instructions I2 and I4 S3: Within an instruction pipeline an anti-dependence always creates one or more stalls Which one of the above statements is/are correct?
The section of the CPU that selects, interprets and sees to the execution of program instructions
What part of the computer interprets and executes instructions that are posed to it?
Assume that we test the performance of two processors, P1 and P2, on a program. We find the following about each: Processor P1 has a CPI of 2 and executes 2 billion instructions per second. Processor P2 has a CPI of 1 and executes 8 billion instructions per second. Which processor has higher performance on this program? (Recall that CPI stands for Cycles Per Instruction.)
The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: The imposition of Governor’s rule in Jammu and Kashmir will not affect operations in the state, according to Army Chief General, even as security forces are looking at higher intensity of operations against terrorists, to force them to ‘hibernate’. These operations will be based on greater level of intelligence from the J&K Police, as compared to what was being generated during the suspension of operations for the holy month of Ramzan. A challenge, however, for the security forces still remains the recruitment of local terrorists. Why? Arguments: I. Meanwhile, data shared by security forces reveal that there are about 210 terrorists currently operating in Kashmir, mainly in the South. Out of this, 65 per cent are locals and the remaining are foreign terrorists.  II. In South Kashmir itself, the maximum number of terrorists belong to the HizbulMujahideen, while some are from the Lashkar-e-Toiba and Jaish-e-Mohammed. III. When a local terrorist is killed during an operation, at his funeral more locals are willing to join terrorism. It is a mob mentality.
On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
