Detailed solution exceeds solution of BLE of ＋ of MCU of low power comsumption
[introduction] below the case that develops in diversity of content couplet net, if volcano erupts to blot out the sky and cover up the earth commonly and all sorts of intelligence terminal come, how will select these products, how to let these products produce completely as different as traditional product life experience, this is a product changes the most primary consideration is nodded, and “ at any time and place forever online ” is the mainest index that measures experience of many AI product to spend.

Introductive
Below the case that develops in diversity of content couplet net, if volcano erupts to blot out the sky and cover up the earth commonly and all sorts of intelligence terminal come, how will select these products, how to let these products produce completely as different as traditional product life experience, this is a product changes the most primary consideration is nodded, and “ at any time and place forever online ” is the mainest index that measures experience of many AI product to spend. So low power comsumption is the technical topic that since companion develops as content couplet net, cannot keep away from all the time.
Exceed technology of MCU of low power comsumption
In before achieve grind have in company article cross a kind to cry with everybody introduction inferior threshold value power comsumption optimizes SPOT technology (Subthreahold Power – Optimized Technology) program of platform of low power comsumption, lowest of its power comsumption can amount to 6 microamper every million hertz, adopt this technique, platform is in inferior below the condition that threshold value stability runs, but reductive the sources of energy uses up nearly 16 times, this is very big to of MCU power comsumption change, the MCU of use SPOT technology (Sensor Hub) platform, make the intelligent equipment of all sorts of batteries power supply OK win time of train in excess specified length await airframe produce the expected result, let at the same time forever the chip support that AI function had on-line to be able to bear the weight of.
At present the admiral machine of product of brand of market top grade, include a hand to use this annulus, watch, earphone to platform manages as power source and pass feeling data to collect processing core mostly.
BLE of low power comsumption
Program of chip of BLE of low power comsumption is very at present much on the market, differ probably the plan of the manufacturer has what can face current market in the round relatively in applied level, also have what be aimed at special market merely, additionally different program also can have difference in RF level, but in consultative core level, no matter be overseas business or indigenous industry, its chip function and function difference are not big, get at the root of the matter is concerned with blue tooth IP. Here the platform of IP of RivieraWaves blue tooth of my citing CEVA, it also is at present the IP of company of chip of a lot of BLE is offerred square, platform of this blue tooth IP offerred comprehensive solution for join of double standard of blue tooth of low power comsumption and blue tooth. So far, use its the chip shipment volume of blue tooth IP has exceeded 2 billion. This blue tooth IP supports newest blue tooth function, the synchronous channel that includes frequency of blue tooth of low power comsumption, search to (AoA ／ AoD) , synchronism of index of random advertisement passageway, regular ad is transmitted, GATT cache and other enhance a function to wait a moment.
Exceed BLE5 of ＋ of MCU of low power comsumption. 2
The actor that BLE is low power comsumption chooses communication plan, those who contain SPOT technology the actor that exceeding MCU of low power comsumption is intelligent terminal unit chooses platform plan, existing blame frequency kind intelligence apparels the product basically is such hardware configuration. And the frequency that contains function of mobile phone accessory kind intelligence apparels to still need to increase power comsumption on equipment greater tradition blue tooth.
Well-known, BT5. 2 before, blue tooth frequency transmits need to pass classical mode of blue tooth A2DP undertakes check the number is defeated as it is said nodding is opposite, and in BLE5. 2 later, LE Audio of frequency of low power comsumption will be OK come true, we need not the frequency business that tradition blue tooth can realize intelligent terminal, this is low power comsumption kind another big breakthrough of application, and the one belt of BLE is muti_function will bring more experiences to frequency business.
