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?
Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
Which of the following statements is/are correct? 1. A system is said to be Finite Impulse Response (FIR), if the output samples of the system depend only on the present input and a finite number of past or previous input samples. 2. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a non-recursive system. 3. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a recursive system.
Consider a system whose input r and output y are related by the equation $$y\left( t \right) = \int\limits_{ - \infty }^\infty {x\left( {t - \tau } \right)} h\left( {2\tau } \right)d\tau $$

Wages of the workers are normally, the proportionality derived from their efficiency. But the concept of efficiency of labour is itself vague such as amount of physical output, output per man hour or output per man shift. But output is not the function of man alone. There are other factors which affect the output. Which among the following is/are not the factor(s) that would affect the output directly?
1. Physical condition of work
2. Nature of machinery
3. Technical process
4. Quality of raw material

In a closed loop system, the process to be controlled is an integrating process with transfer function $$\frac{1}{{2{\text{s}}}}.$$ The controller proposed to be used in an integral controller with transfer function $$\frac{1}{{{{\text{T}}_1}{\text{s}}}}.$$  When a step change in set point is applied to such a closed loop system, the controlled variable will exhibit
