Adopting the method of top - down, the virtual memory is divided into memory mange related unit ( segment unit and page unit ) and protection mode related unit ( protection test unit, debug test unit and exception detect unit ). data buses and control bused are designed separately for all of the units. vhdl codes are written and simulated
Amex86的虛擬存儲器採用自頂向下的設計方法，把虛擬存儲器劃分為地址管理相關單元（又包括分段單元和分頁單元） 、保護模式相關單元（又包括保護測試單元、調試異常單元利異常檢測單元等） ，分別確立其數據通路和控制通路，完成了vhdl的編碼和模擬工作，通過測試程序模擬驗證了其功能的正確性並測定了基本性能。 -
Rtos - 1750 make use of static memory management to implement memory protection provided by page register ' s memory mapping and bpu ( block protect unit ), with which system keep fast reference as well as relatively independence by the technology of strding - mapping. system manages inner interrupt and outer interrupt by priority classing strategy and provides four type timers, which are system timer, software timer, auxiliary timer and real - time timer
系統充分利用1750a提供的頁面寄存器堆的內存映射功能和塊保護單元（ bpu ）提供的存儲器保護功能，採用靜態內存管理方式，既保證了任務之間的相對獨立，又通過跨段映射技術滿足了dcmpofp中的任務快速引用的要求。 -
For the teaching the hardware pwm inverter is designed, including the choice of power module, filter tache, auxiliary power supply, brake unit and protection circuits. in addition data sampling system is contrived with encoder and current / voltage sensors. the control circuit with tms320f240 for the core is presented at last. the circuit includes memory extension, d / a converter digital i / o interface and the interface of the serial port. the way of space vector pwm realization is briefly introduced in this paper
接著，設計了pwm電壓型逆變器，其中包括主迴路功率模塊與濾波環節、控制電源、制動單元及保護電路設計。另外還利用霍爾元件與編碼器設計出數據採集系統。最後，給出了基於tms320f240的最小系統，包括存儲器擴展、串口擴展、數字i o介面以及空間矢量pwm的實現。
