Mention the various IC logic families.Ans. Different IC Logic Families: Digital IC's are fabricated through employing either the Unipolar or the Bipolar Technologies and are termed to as Unipolar Logic Family or Bipolar Logic FamilyI Bipolar Logic Families:Two kinds of operations in Bipolar Logic Families that are:a. Saturated Logic Familiesb. Non-saturated Logic Familiesa. Saturated Logic Families: In this, the transistors in the IC are driven into saturation.1. Resistor-Transistor Logic (RTL).2. Direct-Coupled Transistor Logic (DCTL) 3. Integrated-Injection Logic (I²L)4. Diode -Transistor Logic (DTL) 5. High-Threshold Logic (HTL) 6. Transistor-Transistor Logic (TTL)b. Non-saturated Logic: In this logic, the transistors are not driven to saturation.1. Schottky TTL2. Emitter Coupled Logic (ECL)3. Unipolar Logic Families:II. MOS devices are Unipolar devices
Simply MOSFETs are employed into MOS logiccircuits. The families of MOS logic are(i) PMOS(ii) NMOS, and(iii) CMOS
Whereas in PMOS only p-channel MOSFETs are utilized and in NMOS only n-channel MOSFETs are utilized, in complementary MOS (CMOS), P and N both channel MOSFETs are utilized and are fabricated on similar silicon chip.
Q. Simplify Using K-Map 1. M2 + M3 + M5 + M7 + M12 + M13 + M8 + M9 2. M0 + M2 + M4 + M5 + M8 + M10 + M12 3. F(W,X,Y,Z) = ∑ (0,1,2,4,5,6,8,9,12,13,14)
Blocking and Non-Blocking network In non-blocking networks the route from any free input node to any free output node can always be offered. Crossbar is an best example of non-
What are Addressing Modes Many of instructions that a computer actually executes during running of a program concern movement of data to and from memory. It is not possible sim
Level of any node of a tree is :- Its distance from the root
Q. Explain fundamental instruction set characteristics? Let's look into a number of fundamental instruction set characteristics: The operands can be addressed in memory,
Simplify the given expressions using Boolean postulates Y = (A + B)(A‾ + C)(B + C) Ans. Y = (A + B)(A‾ + C)(B + C) = (A A‾ + AC + B A‾ + BC) (B + C) = (AC + B A‾ + BC) (B + C)
What is reducibility? The primary method of proving some problems are computationally unsolvable. It is known as reducibility. Reducibility always includes two problems
Q. Use of parallel construct with private clause? In this example we would see use of parallel construct with private and firstprivate clauses. At end of program i and j remain
Which approaches do not require knowledge of the system state? Ans. Deadlock detection, deadlock prevention and deadlock avoidance; none of the given require knowledge of the s
