End of the year to summarize the trend of the car navigation market Some minor changes are taking place in the in-vehicle infotainment market, and the growth rate of navigation equipment has exceeded the growth of car audio. GPS applications will begin to differentiate after going through military, instrument navigation to portable navigation (PND). One is to provide positioning services to mobile network devices such as mobile phones, and the other is to target automotive applications, such as C2C (vehicle-to-vehicle information exchange). ), C2I and ADAS (Advanced Driver Assistance System), etc. In the car navigation market, according to ST's estimates, PND shipments in 2008 will increase by 43% year-on-year, from 32 million in 2007 to 46 million. The main growth momentum still comes from the substandard penetration rate of the car navigation market, and the education and promotion of the market is still insufficient. Low-cost OEM navigators (dual-use portable navigators) will open up new markets in mid-level cars. It is expected that by 2012, the market share of in-vehicle navigators will exceed 25% in newly sold cars in Europe and America. From 2007 to 2013, the average annual growth rate of OEM instrument panel built-in navigators will reach 15%, and the growth rate of portable navigators will be 16%. It is expected that the navigation market will reach the level of automotive impact by 2013. The development of navigation technology has surpassed the simple point-to-point route guide to today, and the independent driving assistance system based on map and the collaborative safety system between cars are the next development goals. Integrating advanced driver assistance systems (ADAS) and emergency rescue calls into the navigation system will be standard on all high-end cars. ADAS includes an adaptive speed regulator (AdapTIveCruiseControl, ACC), an adaptable headlight lighting system (AdapTIveFrontlightSystem, AFS), a lane deviation indicator (LaneDepartureWarning, LDW), a blind spot monitoring (BlindSpotMonitoring, BSM), a parking assistance system (parkingassistance) ) And anti-collision safety systems (pre-crashsafetysystems). However, in addition to the introduction of ADAS, in addition to considering the possible impact of ADAS equipment on automobile costs, the stability and safety of equipment operation are also important. Therefore, automotive electronics manufacturers must design cost-related and stable operations in terms of cost and stability. Only when conditions permit, a balance point can be achieved in order to break into the depot supply chain. Emergency calling is a typical application in the current telematics market. The European Union has proposed a pan-European emergency rescue service eCall system. In the event of a traffic accident, the on-board eCall transmitter will automatically send an emergency call to the nearest rescue center. ONStar in the US and Japan have already launched similar services. At present, there are not many vehicles equipped with eCall system, but it is expected to start to tell growth in 2010. Especially in the European market, more than 70% of new cars will be installed in 2013. The United States will also have ordinary cars to join ON-Star, while Japan will install 30%. Looking at the development trend of the navigation market, low-cost, networked car navigation systems (dual-use portable navigators) will occupy a certain share in the low-end car market. A navigation system that integrates ADAS and emergency rescue calls will be standard on all high-end cars. In addition, in order to bring the feeling of the living room at home to the car, the audio and video content playback and file download functions in WMA, MP3, DIVX, MPEG and other formats will be integrated into the car navigation system.
Application-Specific Integrated Circuit refers to an integrated circuit specifically designed to perform a specific computing task. It is very common to use ASIC for mining in the field of blockchain. This article will analyze the principle of ASIC mining and why it should be anti-ASIC.
For Bitcoin, mining has gone through four stages: CPU, GPU, FPGA and ASIC. GPU is naturally suitable for parallel simple operations, so the execution of SHA256 is much higher than the CPU. FPGA is a programmable hardware, because it has a certain degree of universality, so the unit price will be relatively expensive. ASIC has a large initial design investment, but the unit price will be cheaper after mass production. Therefore, if you can determine that the market size is relatively large, the use of ASIC technology will be the most cost-effective.
In a nutshell, mining is running complicated calculations in the search for a specific number. Whether it`s an ASIC miner or a GPU mining rig, mining hardware must run through many calculations before finding that number. In proof of work systems like Bitcoin, the first one to find that number gets a reward - at the time of writing, 12.5 Bitcoins worth around $96,850. That reward will fall to 6.25 Bitcoins in May 2020.

This is the basic principle of ASIC.
There are so many people and powerful computing systems trying to mine Bitcoin that miner groups form to find that number and share the profit. Even more, the faster your hardware, the more you earn. That`s why people who can afford it opt for ASIC miners because it gives them the greatest chance of earning cryptocurrency in exchange for their investment.
Each cryptocurrency has its own cryptographic hash algorithm, and ASIC miners are designed to mine using that specific algorithm. Bitcoin ASIC miners are actually designed to calculate the SHA-256 hash algorithm. In the case of Litecoin, it uses Scrypt. That means technically they could mine any other coin that`s based on the same algorithm, though typically, people who buy ASIC hardware designed for Bitcoin mine that specific digital currency.
