Dollar anchored chip computing power

3. 1) At present, intelligent speakers are put in the cloud to do NLP because the knowledge map and computing power required by the question answering system can not be realized locally. 2) most of the A7 and A53 chips used in the current speakers. 3) according to the local home kit released by Google and Xiaoai teacher released by Xiaomi, there is no problem for A53 to realize local ASR, and some simple It can be expected that NLP in limited fields can execute the corresponding answer / command. 4) if it is a floor sweeping robot, a7 and A53 can be competent if it only needs simple command words. 5) the requirements for the main control chip are mostly determined by the requirements of the application scenario, and the accuracy and anti-interference ability determine the requirements for the chip; If it is a low-power scenario, such as the wake-up and command word functions of TWS headphones, it can be realized with Apollo 2 / 3 of ambiqmicro. If the floor sweeping robot is not sensitive to cost and has high performance requirements (with great noise), then the general MCU is not necessarily suitable. You can consider A7 and A53

on September 18, Huawei released a heavyweight proct, Atlas 900, which brings together Huawei's decades of technological precipitation, is the fastest AI training cluster in the world, and is composed of thousands of ascendant processors. In the resnet-50 model training, the gold standard of AI computing ability, Atlas 900 completed the training in 59.8 seconds, which is 10 seconds faster than the original world record

"imagenet-1k data set" contains 1.28 million images, with an accuracy of 75.9%. Under the same accuracy, the test results of the other two mainstream manufacturers in the instry are 70.2s and 76.8s respectively, and the atlas 900 AI training cluster is 15% faster than the second. Hu houkun said: the powerful computing power of atlas 900 can be widely used in scientific research and business innovation. For example, astronomical exploration, oil exploration and other fields all need to carry out huge data calculation and processing. Originally, it may take several months, but now atlas 900 is just a matter of seconds. The thousands of integrated shengteng processors in atlas 900 are the commercial shengteng 910 some time ago

5. On shore Chinese currency USDCNY: China's Chinese mainland's spot rate is announced by the people's Bank of China authorized by the China foreign exchange trading center.
offshore RMB exchange rate USDCNH: the so-called offshore RMB market is the market for Renminbi deposits and loans outside the Chinese mainland.

the pricing mechanism of RMB exchange rate in domestic market is different from that in offshore market
the exchange rate between RMB and foreign currency in China is still not completely free, and the exchange of RMB and foreign currency needs to meet the regulatory conditions of safe. Both of them are based on real demand, so the exchange rate is more determined by the supply and demand of RMB and foreign currency under the background of real demand
the RMB exchange rate in the offshore market is not subject to domestic regulation. The transaction is free convertibility and market-oriented pricing. It not only includes the principle of overseas real demand, but also reflects the speculators' speculative demand. Therefore, the RMB exchange rate outside China will be different from that inside China, and sometimes it will be quite different
however, the pricing power of RMB exchange rate is still in China, so although there may be a price difference between domestic and foreign exchange rates, the price difference will not be too big, and the too big price difference will not last for too long. The reason is that if there is a price difference at home and abroad, domestic customers can use RMB cross-border settlement method to choose a better overseas exchange rate for foreign exchange settlement and sales under the background of convenient RMB cross-border settlement. Such arbitrage transaction will result in the domestic foreign exchange gap being wiped out.

6. No, since the Bretton Woods system, the US dollar has been decoupled. How can it be anchored?

7. Not trustworthy, too unrealistic.

8. The achievements of new China: 1. Political achievements: the return of Hong Kong and Macao, a century of humiliation; One belt, one road, to promote common development and achieve common prosperity. Asian investment banks, led by China, break the monopoly of Asian infrastructure by the Asian Development Bank controlled by Japan and the United States. The G20 summit in Hangzhou will promote the sustainable development of the world economy. Permanent members of the United Nations, one vote veto. The 70th anniversary of the victory of the Anti Japanese War 2. Economic achievements China's GDP exceeds 10 trillion US dollars, which is a member of the 10 trillion club in the world and twice the GDP of Japan. West to east natural gas transmission, environmental protection and haze elimination. The south to North Water Diversion Project is unprecedented. The Three Gorges Dam, the world's first Tibet Tianlu, is a giant dragon on the roof of the world. High speed rail is 20000 km, accounting for 60% of the world. The output of iron and steel is 1.6 billion tons in the world, and China accounts for 800 million tons. China has 120000 kilometers of expressways, accounting for 52% of the world's total, which is the largest in the world. There are six of the world's largest Hong Kong Zhuhai Macao cross sea bridges. The foreign exchange reserves of the Three Gorges Dam, the first in the world, have remained the first in the world for N years. China and the United States have too many, so China has been recing its holdings of US dollars. Others, such as computers, TVs, refrigerators, tablets, air conditioners and mobile phones, account for more than half of the world's proction. 3. The achievements in sports, Beijing Olympic Games, the best Olympic Games in the world, can be said to be unprecedented. At the Rio Olympics, China did not play well and won the top three gold medals. Beijing Olympic Games, China is the absolute champion of the Olympic gold medal list. Breakthrough in Basketball - Yao Ming. Liu Xiang, who won three gold medals, cheated the men's football team of the two Olympic Games to achieve a historic breakthrough, and entered the 2002 South Korea / Japan World Cup diving. From the era of dream team to the super dream team with the first gold medal of China's team in the Rio Olympic Games, China swept the world table tennis arena. China's women's volleyball team rose from Dongshan, won two World Championships, and even won the gold medal of the Rio Olympic Games, Achievements in science and Technology China Tianyan, the world's largest telescope Beidou satellite, ranks second in the world.

According to the different sizes of Koi, there are different requirements. The general stocking density of fish pond can refer to the density table of Koi in fish pond

1, 60 cm × 30 cm × There are 6 Koi (Cyprinus carpio L.) with body length of 15 cm-20 cm that can be stocked at 15 cm

2, 90cm × 30 cm × 8 can be raised in 50 cm range from 15 cm to 20 cm

3, 110 cm × 30 cm × 50 cm can be stocked 15 cm - 20 cm of 10

common carp is a kind of fish with strong adaptability, and Koi also retains this characteristic. They can be raised anywhere from small fish tanks to outdoor ponds, and they will soon grow to 30 cm long or larger, so a traditional indoor fish tank is not as good as a round plastic basin. Koi is a cold water fish, so it is better to raise Koi in hot places in summer with a depth of half a meter or deeper

extended data

the environmental requirements of Koi

Koi and goldfish have no strict requirements on water temperature and water quality. The suitable temperature range is 2 ℃ ~ 30 ℃, but it can't resist the sudden change of water temperature. If the temperature difference suddenly exceeds 2 ℃ ~ 3 ℃, Koi will have discomfort, and the optimum water temperature is 20 ℃ ~ 25 ℃; It needs sufficient oxygen and is suitable for living in the water environment with slight alkalinity and low hardness

koi is an omnivorous fish, which can be eaten by mollusks, fragments of higher aquatic plants, benthos, even tiny algae or synthetic pellet t
