What's The Use Of Chips In Mobile Phones? Why Does Everyone Want To Be "stronger"
Old Mai Has Received A Task To Tell You About Popular Science. How Do Mobile Phone Chips Determine The Performance And Experience Of Smart Phones? After Studying A Pile Of Materials, I Found That If I Directly Popularized These Technical Terms And Analyzed The Principles And Functions Of Modem, GPU, AI, ISP And CPU, It Is Estimated That You Would Not See It For A Long Time. It Suddenly Occurred To Me That My Old Profession Is Medicine And I Have A Better Understanding Of Human Body Structure. Then I Will Use The Analogy Of Human Body Structure To Tell You About The Relationship Between Chips And Smart Phones.
Chip Is Brain + Nerve
Probably In Most People's Cognition, The Chip Generally Represents The CPU. Because In The Traditional PC Era, The Computer Case Has Enough Space, Each Module Is Independent And Separated, And The CPU, Graphics Card And Network Card Are Well Installed. However, In The Era Of Smart Phones, All Functions Have To Be Compressed Into Square Inches, And The Chip Has Changed Greatly From A Single Processor To A System On Chip SOC (system On Chip).
Taking Xiaolong 8 As An Example, In Addition To The CPU For General Computing And GPU For General Programming, The Flagship Mobile SOC Also Includes Some Special Programming Units, Such As DSP And AI Engine, As Well As More Signal Processing Units, Such As ISP Image Signal Processor For Image Processing, Vpu Video Processing Unit, DPU Display Processing Unit And APU Audio Processing Unit. Moreover, The SOC Module Is Still Expanding To Accommodate The Operation And Management Of More Functions Such As Network Communication And Charging Management. This High Integration Also Brings Faster Data Flow And Coordinated Management. If The Mobile Phone Is Compared To A Person, The Chip Is The Brain And Nervous System, Which Is Responsible For Collecting And Coordinating The Information Of Various Sensors, Integrating Operation, Analysis And Response. Whether A Person Is Smart And Capable Depends More And More On The Ability Improvement Of The Whole SOC. Otherwise, Even With More Cameras And Larger Sensors, There Is No Practical Significance. Smart Phones Have Long Passed The Era Of Heap Peripheral Hardware, But Pay More Attention To Chip Integration And Algorithm Optimization. It Must Be Admitted Here That In The Android Mobile Phone Camp, Qualcomm Has Always Led The Development Of High-end SOC. Next, We Will Continue To Compare With Humans To See What Surprises Xiaolong 8 Will Bring.
Give You A Pair Of Stronger Eyes
There Is An Old Saying That The Eyes Are The Windows Of The Soul. If The Soul Is Strong Enough, First Look At Whether The Eyes Are Clear Enough. Therefore, Today's Flagship Mobile Phones Have The Ability To Spell Images, Because In Addition To Taking Photos And Recording, The Camera Is Also An Important Information Entrance. Scanning Code, Scanning And Even Participating In The Identification Of Biological Information Indirectly Determine Your Use Experience.
In Order To Facilitate Your Understanding, We Will Continue To Popularize The Process Of Mobile Phone Imaging Based On The Principle Of Human Eye. The External Lens Is Equal To The Cornea Of The Eye, CMOS Is Equal To The Retina, ISP Image Signal Processor Is The Cerebral Cortex Responsible For Visual Information Processing In The Brain, And AI Algorithm Chip Is The Middle Cortex For Processing Details. The Complex Collaboration Between Them Has Completed The Photos And Videos We See. How To Improve The Underlying Ability Of "eyes"? We Need To Start From The Following Aspects.
Increase The Optic Nerve To See More Information
Xiaolong 8 Improves The Data Capture Capability Of ISP From 14 Bit To 18 Bit, Which Can Be Understood As Retinal Enhancement. At Present, 3.2 Billion Pixels Are Imaged Per Second, 9 Billion Pixels Are Processed In Real Time, And 108 Million Pixels Are Captured By A Single Camera. What Is The Concept Of These Parameters? Back To Your Photography Experience, You Can Take Photos Faster And Capture Moving Objects More Clearly. Press The Shutter Once To Get 30 Picture Information, Leaving Enough Space For Later Image Processing.
With More Information, You Need More Computing Power. Xiaolong 8 Series Mobile Platform Has Been Upgraded From The Previous Dual ISP To The Three ISPs Supported By Xiaolong 8. With The Collaborative And Concurrent Capability Of 18 Bit Three ISPs, The Mobile Phone Equipped With Xiaolong 8 Can Make Multi Subject Fusion Photography, That Is, When You Take Photos, You Can Not Only Switch The Main Camera Or Wide-angle Lens According To The User's Needs, But Automatically Call The Advantages Of Different Lenses To Shoot At The Same Time And Optimize At The Same Time, So As To Improve The Clarity And Picture Details Of Photos And Repair Potential Distortion, Noise And Other Defects. For Example, The Ultra Wide-angle Photos Taken By Glory Mobile Phone In The Above Figure Are Clear And Delicate Although The Indoor Light Is Not Ideal.
Improve Computing Power And Make Analysis And Synthesis Faster
In Addition, The Implementation Of Three ISPs Can Also Support Super Multi Frame Engine, So That The Number Of Synthetic Photos Taken By Mobile Phones Can Be Increased From 6 To 30, Which Is Equivalent To A Scene Picture. You Were Shown It 6 Times, But Now You See It 30 Times, The Information In Your Mind Must Be Richer And More Accurate. Especially In Terms Of Face Details, It Can Better Identify And Optimize, And Improve The Natural Beauty Of The Portrait. This Is Different From Simple Beauty, But Deep Learning And Understanding.
This Photo Is A Close-up Of The Cat Captured After Five Times Zoom, And When The Indoor Light Is Insufficient And The Background Is Chaotic, The Camera AI Can Not Only Recognize The Cat And Carry Out Targeted Optimization, More Clearly Show The Hair Details And Ensure The Film Effect To The Greatest Extent.
Computing Power Is IQ, And Algorithm Is Eq
IQ Mainly Reflects People's Observation Ability And Calculation Ability, Just Like The Calculation Ability Of ISP. EQ Mainly Reflects The Ability Of Understanding, Application, Control And Regulation, Which Is Just Like The Understanding And Application Of AI Chip.
The Application Of This Ability Is Also Very Common. The Most Direct Effect Is The Effect Of Background Virtualization. Because The Space Of Mobile Phone Is Extremely Limited, It Is Impossible To Achieve The Optical Virtualization Of Traditional Camera, But We Hope That Mobile Phone Photography Can Obtain A Better Spatial Level. At This Time, We Can Highlight The Powerful Role Of Special AI Hardware Unit Integrated On Mobile Phone SOC. Especially In Video Shooting, It Tests The Real-time Computing Ability. Xiaolong 8's 7th Generation Qualcomm AI Engine Is Composed Of Hexagon Processor, Tensor Accelerator, DSP And Its Own Memory. It Is Equivalent To Another Auxiliary Brain, Bringing Users A More Intelligent Image Shooting Experience. To This End, I Also Took Glory Magic 4 To Shoot The Night Scene. The Ability Of AI Engine Is Presented In Various Situations Such As Complex Night Scene, Dark Light And Long-distance Shooting. Finally, The User Can Produce The Film Easily, Ensure The Clarity And Quality, And Greatly Improve The Color Accuracy.
Not Only Smarter, But Also More Loyal
Through The Above Analysis, You Can Feel The IQ And EQ Level Of Xiaolong 8. However, As A Smartphone Serving Us, It Accompanies Us For More Than 8 Hours Every Day And Holds A Large Number Of Important Personal Privacy Data. Security Has Become A New Topic.
Data Encryption Of Internal Chip Layer
It Has Always Been Thought That Mobile Phone Security Only Lies In The Software System, But Xiaolong 8 Has Introduced Security Features Into The Chip Hardware System. For Example, Qualcomm Hypervisor, A Deep Protection Layer, Is Introduced Under The Android Operating System. Its Task Is To Isolate And Protect The Data Of Various Applications And Services, So As To Prevent The Data Of Application A From Being Maliciously Retrieved By Application B. Sandbox Mechanism Similar To Hardware.
