【MCU 內嵌三種加速器，極致效能】

微控制器 (MCU) 為何要內嵌三種加速器？——ART Accelerator (Adaptive Real-Time memory accelerator)、CCM-SRAM (Core Coupled Memory) 常規加速器和數學加速器。各有什麼職責？
●ART 自適應即時記憶體加速器：針對動態快取 (Cache)，彌補高速 CPU 與相對低速 Flash 指令讀取之間的不一，當 Flash讀取速度夠快、CPU 會隨之加速；
●CCM-SRAM 常規加速器：針對靜態快取 (Cache)，當 SRAM 被其他硬體使用時，CPU 可使用 CCM 達到零等待，可加速對時間要求較高的程式執行，亦可充當額外的記憶體；
●數學加速器：以硬體加速運算性能，對於馬達的向量控制 (Field-Oriented Control, FOC) 等多數值演算法可明顯提高運算速度並節省能耗。

什麼樣的 MCU 如此大手筆？猜一猜！

【無編碼、無感測器驅動控制，一樣可實現節能！】

磁場導向控制 (Field-oriented Control, FOC) 是利用調整變頻器 (VFD) 的輸出頻率以及輸出電壓大小、角度，控制三相交流感應馬達或無刷直流 (BLDC) 馬達的輸出，可「個別控制」馬達的磁場及轉矩為其優點。

完全集成 FOC 演算法的三相無編碼、無感測器驅動器 (柵極驅動器)，可實現最佳效率和雜訊性能，讓設備可在靜止狀態、風車狀況甚至反向風車狀態下優化電機啟動性能——透過類比、脈寬調製 (PWM) 或時脈輸入控制馬達轉速 (RPM)，且能藉控制可選閉環速度，對「RPM／時脈頻率」進行編程，是吊扇、底座風扇、浴室排氣扇和家用電器風扇和幫浦的理想選擇。

#朗格Allegro #QuietMotion #AMT49406

Model name of bicycle (small leisure motorcycle) with motor to which Honda Motor Co., Ltd. is doing manufacturing sales monkey (MONKEY). The form of the model put on the market by Kon soon will be AB27. It is called generally fourMINI with the gorilla etc. of the sisters car.
The Z100 type of the leisure motorcycle announced in the Tokyo Motor Show in 1961 was a cradle, and, at first, it began to be manufactured as a play equipment of the amusement park that HONDA had been managing. And, overseas export of CZ100 that is the restyling version in 1964 will start, and development be done from popular in the customer as for a domestic-oriented specification of running in the public road.

Edit MONKEY

The Z50M type of domestic-oriented that was first MONKEY was put on the market in 1967. The body of CZ100 was misappropriated at first, and ..five-inch tire.. composition named Riget (the suspension none). The installed engine is air cooling 50cc single cylinder based on Suparcab, and the valve mechanism has been changed from OHV of CZ100 to OHC with Cab.

Moreover, the fold function of the steering wheel that one of the features included the carburetor and now with the tank cap and the drain cock that attached the fuel leakage prevention device on the assumption of installing in the vehicle was installed.

It changes to a rear suspension and equipment and the knobby tire of a rear career receiving the change that enlarges the body composition a little in 1969, equipping with eight-inch tire and the reception desk suspension, and repeating the minor change afterwards. The gear put on the market in 1978 is changed at three velocities.

Sales was a long seller that followed Cab, and a special vehicle of a lot of manufacturing number limitations was put on the market until a lot of arriving at the Gold specification (1984 and 1996) with the motorcycle of Japan as for the kind of the body color put on the market by a past model etc. (The color order car is excluded).

The revival by correspondence from a popular model it to the restriction is expected though the end of production is being notified by strengthening the car exhaust emission regulations in September, 2007 by HONDA in 2008.
Origin of car name

It is respectively commemorating primates and apelike ape gorilla. There is a theory of having been named from the field monkey highway near Tama Tech where Z100 was put at that time besides a general theory that externals of man who is driving look like the ape about the monkey of the car name decided when putting it on the market, too.
