Loop unrolling is used because having a loop means incrementing the counter and checking the condition everytime which is an overhead. But most importantly, it reduces branch penalties in architecture that supports pipelining.

3:40 यह बिन्दु loop fusion पर भी लागू होता है। मैं हमेशा असमंजस में रहता था, कि loop दो भले या एक, क्योंकि theoretically कोई अंतर नहीं है। पर आपकी इस टिपण्णी ने और पाठ्यक्रम के इस विषय ने इसका निर्णायक उत्तर दे दिया है। > _"having a loop means incrementing the counter and checking the condition everytime which is an overhead"_

6:17 आप loop unrolling की बात कर रहे हैं, पर ध्यान रहे कि code में ऐसा मत कर देना 😂 क्योंकि ये वाली optimization compiler स्वयं से करता है, source code का इतना कोई लेना देना नहीं है इससे

If loop invariant is used then don't we are getting 2 different values 1. If statement is moved outside loop on low freq region . 2. Inside loop (high freq) ?????

सर! क्या लूप अनरॉलिंग में सिम्पल एक्जीक्यूशन में मेमोरी कंज्यूम नहीं होगी? मतलब स्टेटमेंट बार बार लिखने से। कृपा रिप्लाइ अवश्य दें। धन्यवाद्
