【工業應用之浮點運算,MCU or DSP?】

工業用的伺服或永磁同步馬達由於需要精準控制或回傳資料,讓微控制器 (MCU) 掀起浮點運算風潮;尤其是 ARM Cortex-M4 架構因性價比高,且在生態系統佔有先進優勢,頗具「共主」之姿。不過,若需動用「運動軌跡規劃」的高階馬達,冀使運轉較為平滑,MCU 恐力有未逮,或須仰賴專業的數位訊號處理器 (DSP) 方能擔當大任。

以往要將浮點精密度和動態範圍引入馬達工業應用,成本相當高;但當 DSP 融入浮點運算特性後,處理效能預估能較一般 DSP 高出三成,足以設計和執行最複雜的演算法。此外,封裝方式若具外部記憶體匯流排介面,還能符合需要額外 SDRAM 的應用;再者,若有脈寬調變 (PWM) 輸出功能,還能支援馬達控制和其它功率逆變器應用,適用於量測、再生能源和智慧電網應用。

About author
2002年,憑藉獨特敏銳度察覺到電子業界需求,《COMPOTECHAsia電子與電腦》於中國大陸取得《COMPOTECHChina》月刊發行權,為初到海外發展及當地讀者出具最具前瞻性且中肯的觀察,具有相當影響力,也成為一流國際大廠競相展示研發心血的首選。 2006年,有鑑於網路環境日趨成熟,《COMPOTECHAsia電子與電腦》再度領先同業,首創線上視頻平台CTOV (COMPOTECH Online Video)。自此,成為整合紙本、網站、電子報及線上視頻的全方位媒體。 2016年,為貫徹市場應用及開發技術的連結並擴大群眾基礎,陸續展開 Facebook、Twitter、LinkedIn 等社群平台經營。 「就市論勢、就勢論市」是我們的信念。我們將於每週一、三、五下午在 FB 分享生活中隨處可見的科普知識,以平易近人的方式,用不一樣的角度觀察市場趨勢和技術走向,並不定時穿插轉載網路精彩佳作或趣聞。記得設為「搶先看」哦! “COMPOTECHAsia/ China” issue on 8th monthly. It is the dependent media which focuses on electronic industry situation, end user market, and technology trend. The monthly magazine has become the main channel to get professional information for engineers, purchaser, R&D employees and decision-making management. We perceived the demand of electronic industry and strive to get the distribution rights of “China Edition” in Mainland China in 2002. It gives a lot of prospective and proper observation for the overseas workers and local readers. Gradually, COMPOTECH is getting to be the powerful. Nowadays, COMPOTECH is the first-choice platform for the first-class firms to display their R&D results. Furthermore, in 2006, we were ahead of our competitors to build the CTOV platform (COMPOTECH Online Video) due to the mature internet environment. Since then, COMPOTECH has become the integrated media. For having a thorough knowledge of market applications and technology migration, as well as expanding the base of the masses, we begin to manage the Facebook, Twitter and LinkedIn etc. in 2016.
