#嵌入式系統 #微控制器MCU #資安

【MCU 再進化】

微控制器 (MCU) 越來越強大，對於運算、儲存、加速、智財保護及電源效率亦樹立新標竿：

◎兼容雙精度／單精度浮點單元 (FPU)；

◎高速緩存零等待，提高外部儲存器的執行性能；

◎雜湊 (Hash) 硬體加速／加密，資安防護更緊密；

◎安全韌體安裝 (SFI) 的嵌入式安全服務，初始編程時可驗證、保護軟體 IP，並提供安全啟動／安全韌體更新 (SBSFU)；

◎多電源域架構可為不同電源域設置低功耗模式以優化電源效率，另嵌入式開關模式電源 (SMPS) 可縮小電源電壓，也可為外部電路供電或與低壓差穩壓器 (LDO) 結合用於特定用例。

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.
智能系統設計／應用工程師、產品／專案開發主管、元器件／零組件／準系統採購者的交流園地，於每週一、三、五下午分享【科技應用取向】的趨勢議題。

影片引用自 Starlition Tsui
這張電路板是台灣駭客年會(Hitcon) 2017 Badge
之前一直以為是用MTK 7688 (Mips core) 架構等於一個完整linux .
標配為4~8MB Flash, 16~64MB DRAM.
看到影片資料才發現是MTK7697
Cortex-M4 with FPU 192MHz
Dram 做在MCU內 352KB ,
非常類似STM32 不過mtk強項在於wifi與mcu的整合.

我們的理念是，做個 Reverse engineering Lab 要公開跟分享真實有效的 IT 技術與原理，才能驗證技術是否正確。 並且嘗試各種不同技術、知識、發想概念的組合來測試能否得到更佳的結果
這是個IT實驗室在Storage 、Information security、 Networking 、Embedded 造業(Karma)與解業的故事及心得
