The main points about Single Accumulator based CPU Organisation are:
In this CPU Organization, the first ALU operand is always stored into the Accumulator and the second operand is present either in Registers or in the Memory.
Accumulator is the default address thus after data manipulation the results are stored into the accumulator.
One address instruction is used in this type of organization.

we are are so fortunate to have a teacher like you. Brilliant explanation sir.
Many thanks
You are right
I am in class 11, but i understood everything you said. I didn't saw any teachers like you. You are amazing sir.
Thank you dear.. Love and blessings
Thank you so much for this free resource! Started learning how to build Computers as a Hobby,
and now I finally know how to reduce my Instruction Set to 8-bit with fewer compromises.

Your videos are better and concise than American university lectures. Please make videos on questions for interview preparations in COA and OS.
विस्तृत नोट्स: Single Accumulator CPU Organization
1. CPU Organization चे मूलभूत घटक (Basic Components):
A) Accumulator:
- हे एक विशेष register आहे
- साधारणपणे 16-bit चे असते
- ALU कडून येणारा डेटा temporary store करण्यासाठी वापरतात
- सर्वात जलद आणि महाग memory unit आहे
B) Program Counter:
- पुढील instruction चा memory address store करतो
- CPU ला सांगतो की पुढची instruction कुठे आहे
- Sequential execution साठी महत्वाचा
C) Common Bus System:
- सर्व components एकमेकांशी connected असतात
- तीन प्रकारचे signals transfer करतो:
* Data signals
* Address signals
* Control signals
2. Single Address Instructions ची कार्यपद्धती:
A) Instruction Format:
- Mode: डेटा कुठून घ्यायचा ते सांगतो
- Opcode: कोणती operation करायची
- Operand: एकच address/value handle करू शकतो
B) Example समजावणी (X = A + B):
```
Step 1: LOAD A (Accumulator मध्ये A load करा)
Step 2: ADD B (B ची value add करा)
Step 3: STORE X (result X मध्ये save करा)
```
प्रत्येक instruction मध्ये फक्त एकच operand असतो
3. Cost Effectiveness:
A) Register आणि Cost चा संबंध:
- जास्त registers = जास्त खर्च
- Registers हे सर्वात महाग memory components असतात
- Single Accumulator design कमी registers वापरतो
4. Addressing Modes:
A) Mode चे महत्व:
- Operand कसा interpret करायचा ते ठरवतो
- विविध प्रकार:
Direct addressing
Register addressing
Memory addressing
5. फायदे (Advantages):
- Cost-effective design
- Simple architecture
- छोटी instruction length
6. मर्यादा (Limitations):
- एका वेळी एकच operand handle करू शकतो
- एक operation पूर्ण करण्यासाठी multiple instructions लागतात
- Performance relatively slower असू शकतो
7. प्रॅक्टिकल वापर (Practical Usage):
- Basic computing tasks साठी योग्य
- Low-cost systems साठी perfect
- Simple operations साठी efficient
महत्वाचे मुद्दे (Key Points):
1. Single Accumulator हे basic CPU organization आहे
2. Cost-effective परंतु multiple instructions require करतो
3. एका वेळी एकच operand handle करू शकतो
4. Simple operations साठी perfect आहे
5. Limited registers वापरून maximum efficiency मिळवतो
This detailed mixed-language explanation helps in better understanding the concept of Single Accumulator CPU Organization, especially for Marathi-speaking students studying computer architecture.
thanku sir g very nice and explain with simple way...............
Thankyou sir, our college professor made this subject seem very hard to understand and now I'm getting it in one go.
Outstanding sir
Superb 👌👌👌👌
Thank you sir for your all videos they are very helpful to do study
I am a bca student thank you sir your video is very helpful for me thanks a lot sir
you're the best teacher on RUclips, please keep making this amazing content!!!
Great sir 👌
Sir you are great 👍👍❤
Thank You so much... Sir... 😊👌....
Your Explanation.... 👌...Ap Best ho Sir... 😊👌...
YOU ARE GAWD SIR
🤞🤞
Amazing sir😍😍
Nice explanation
Sir, you are the best teacher.
Again thanks
Nice shirt with helpful video sit , Thank You👍
You are great sir 👏
please complete the data structure series that's one of the most important subjects for gate
Thnku sir
Thnku soo much
Vryb nyc sir thanx thanx alot
You are great Sir ji
Thanks sir g 👍
Thank you sir
v nice
Nice explaination sir bs todha notes bhi provide krden😊
samj me to kuch nhi aya lekin achha tha
Thankyou sir
Sir please upload numerical on each topic so that each theory will cleared...... Without numerical theory is acting as boring👏👏👏👏
Self referential note : single accumulator org. Starts at 1:20
South people assembe here ..😅😅
Sir plz complete the series of *computer architecture*
said the right thing
Very good Lectures but please give us time to capture complete board picture before starting next video.
Good explanation sir, I just wanted to point out that Your videos are not sorted properly... I mean that lecture 14 which is having the question must be after the explanation of all 3 addresing scheme videos... Its a request to properly sort them according to the topics so that we can see all videos in a proper sequence, thanku have a nice day :-)
Ye sub bohot hard hai
PLZ sir CO ke lectures thoda fast daliye
sir please explain fixed length instructions expand opcode technique 😊
Description of FALCON-A and EAGLE using RTL please explain these topics
First
i have a question , well if we have more than one operand for example one present in a register , and one immediate , then how are we going to set the addressing mode
immediate value will be the operand and the in regiter we have get it through the add.mode ...hope this will help you.
Can someone suggest a channel to understand numericals of COA? Please help.
Sir how can I contact you?
Yeh wala Thora samja nhi ap ne toi phele bola tha ki sari khani chalu hoti hai program counter register se , fir o jata hai address register us instructions ka address khana Mai memory hai fir memory se data register par jata fir us le alu , but apne toi ismai data register and adress register Kia e nei, please koi yeh doubt solve kar do
Sir,
Is "Store" is a single address instruction( Str x
The instrruction is actually STORE X (Here X is an address.. Behind the scene it works like - MEMORY[X] = AC(accumulator))
Is this playlist enough for gate2024
Hello sir, Im doing MCA 1st year, can i write GATE 2020? If yes can i get a chance to go for PSU jobs in Computer Science
Hi Anand, I've completed my MCA this year so I can answer your question. You can eligible for GATE only when you are either in final year or passout.
@@kajolnimesh483 thanks for the info.
Sir aap kabhi accumulator ko A likhte hain aur kabhi AC. Aisa na karien, confusion hoti hai. ❤
8085 microprocessor mein register A hi ACC ka kam karta hai
06:02 if we have address of only only operand thn how the f we got B
The instruction is supposed to have only one address.... so in accumulator one value is stored.... and then in next instruction(Add b) b is given so it adds the value of b to the value that is already present in accumulator
Bhia assembly language ke bare me btao.
ok
organization hota hai bro.....
Aap notes kyu provide nhi krate🤦
Notes ki kmi mujhe bhi feel hoti hai 😢😅
Kab se bhai exam 15 se?
Aap notes khud kyon nahi bana lete.
Sir yeh 8 bit 256 kaise jo gaya
2^8=256
Sir ap acha smjhaty but plzz itni short video na bnaya krain ak topic or us sy related chezun ko ak ee video man khtm kia krain q k ni to phr insan ki understanding ka sequence tot jata hy... Jaisy isi video man ee ap in teeno types ko define krty
Bilkul nahi sir aapki short videos ke hi karan hum bore nahi hote or aapka pura playlist deakhte hai apne subjects ko complete karne ke liye. Very nice work sir keep it up😎😎🤘🤘
can u provide notes
Notes v provide kar do ...
Kuch bhi samj nii ayaa 😂😂😂..
thanku sir g very nice and explain with simple way......
Thank you sir
