Give microinstructions for the following register reference instructions of the basic computer: (i) CMA (ii) SPA In a basic computer, register reference instructions  are those that directly operate on registers without memory access. These are executed when the control unit  detects an instruction with I = 0 and D7 = 1 (indicating a register reference operation in the instruction decoder). ADVERTISEMENT Each microinstruction specifies control signals that direct the data flow within the processor. (i) CMA (Complement Accumulator) The CMA (Complement Accumulator)  instruction takes the current value in the Accumulator (AC)  and replaces it with its bitwise complement . Microinstructions for CMA: AC ← AC' (Complement each bit of AC) SC ← 0 (Reset sequence counter to fetch next instruction) ADVERTISEMENT (ii) SPA (Skip if AC is Positive) The SPA (Skip if AC is Positive)  instruction checks the sign bit (leftmost bit) of the Accumulator (AC) . If the sign bit is 0 (indicating a positive value or zero), it increments the Program Counter (PC) to skip the next instruction. Microinstructions for SPA: If (AC(15) = 0) then PC ← PC + 1 (Check sign bit and increment PC if positive) SC ← 0 (Reset sequence counter) These microinstructions define the control logic needed to execute the given instructions in a basic computer architecture . 🚀

Perform the following conversions to the indicated bases: (973) 10 = (?) 5 (F23A) 16 = (?) 8 (10110.11) 2 = (?) 10 Let's perform the given conversions step by step. 1. Convert (973)₁₀ to Base 5 We repeatedly divide 973 by 5 and record the remainders. 973÷5=194 remainder 3 194 ÷ 5 = 38 remainder 4 38 ÷ 5 = 7 remainder 3 7 ÷ 5 = 1 remainder 2 1 ÷ 5 = 0 remainder 1 Reading the remainders from bottom to top, (973)₁₀ = (12343)₅ . ADVERTISEMENT 2. Convert (F23A)₁₆ to Base 8 First, convert from hexadecimal (base 16) to binary. F=1111, 2=0010, 3=0011, A=1010 So, (F23A)₁₆  in binary: F23A=1111 0010 0011 1010 Now, group into triplets from right to left for conversion to octal: 1 111 001 000 111 010 Converting each triplet to octal: 1=1,111=7,001=1,000=0,111=7,010=2 So, (F23A)₁₆ = (171072)₈ . ADVERTISEMENT 3. Convert (10110.11)₂ to Base 10 We expand the binary number using powers of 2. Thus, (10110.11)₂ = (22.75)₁₀ . Final Answers: (973)₁₀ = (12343)₅ (F23A)₁₆ = (171072)₈ (10110.11)₂ = (22.75)₁₀

ADVERTISEMENT Candidate Profile:Background:  General Engineering Male (GEM) Academics:  10th – 89.8% | 12th – 84.8% | Graduation – 69.1% CAT Percentile:  99.93 Panel Composition:  3 Members – 2 Female (P1, P2), 1 Male (P3) Interview Questions & Responses P2:  Naman, tell us something about yourself. (This interview was after a month-long gap since my last one, so I was slightly unprepared for my usual answer. I mentioned my graduation and work experience but forgot to cover my hobbies.) P2:  Do you know of any recent M&A (Mergers and Acquisitions) in the pharma industry? Not very recent, but Ranbaxy was acquired by Sun Pharmaceuticals. P2:  Why do you think M&As take place? To capture market share and reduce competition. I explained with an example of Flipkart acquiring eBay India (which had happened just a day or two before the interview). P2:  Okay, now P1 will give you your extempore topic. (I had butterflies in my stomach, hoping the topic wouldn't be too difficult.) Extempore P1:  You have to speak on the topic "Namaste"  for a minute. (I was relieved to get a simple topic!) Spoke about how "Namaste" is very closely associated with me since it is the meaning of my name. Explained that it is the first word many foreigners learn when they come to India. Mentioned that it is used to greet people and show respect, and that it is synonymous with "hello." Concluded with "That’s all I can think of." P3:  (First time speaking, with humor) "Kisi ko bhagana ho toh bhi bolo Namaste."(Everyone grinned.) P1:  Tell me three women entrepreneurs. I could only name one – Kiran Mazumdar Shaw. P1:  Which organization does she lead? Biocon. P1:  Tell me some industry experts instead. Indra Nooyi (PepsiCo) and Arundhati Bhattacharya (SBI). P1:  How long have they been working in their respective organizations? I don’t know, ma’am. P3:  Why MBA? Talked about my career plan and family business. P3:  What is the turnover of your family business? Told. P3:  How do you judge a company’s performance? Talked about financial statements, mainly the income statement and balance sheet, and what each of them represents. P3:  Do you know any financial ratios? Initially said I didn’t have much finance knowledge, but then suddenly remembered and blurted out: "PE Ratio, sir. The Price-to-Earnings ratio."   (Sigh of relief!) P3:  IIM Calcutta results were announced yesterday. Did you convert? Didn’t convert, sir. P3:  Why? Didn’t answer a couple of questions well, and CAT score weightage is lower there. P3:  But you’ll get the benefit of weightage here. Yes, sir! Closing Remarks Verdict:   Direct Convert! 🎉
