  • ARM手機MID平板方案詳解

    ARM核心是主控SOC中的重要部分,系統的日常應用都由ARM核心來完成,因此ARM核心的效能很大程度上跟用戶體驗有關。ARM公司一般用DMIPS/MHz來標稱ARM核心的性能。DMIPS是Dhrystone Million Instructions executed Per Second的縮寫,反映核心的整數計算能力。但Dhrystone算法代碼本身比較叫,可以完全放到Cache中執行,因此反映的只是核心能力,并不能反映緩存、內存I/O性能。

  • Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in A

    Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs new Cortex family. With high performance and power efficiency, it targets a wide variety of mobile and consumer applications including mobile phones, set-top boxes, gaming consoles and automotive navigation/entertainment systems. The Cortex-A8 processor spans a range of performance points depending on the implementation, delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding consumer applications and consuming less than 300mW for low-power mobile devices. This translates into a large increase in processing capability while staying with the power levels of previous generations of mobile devices. Consumer applications will benefit from the reduced heat dissipation and resulting lower packaging and integration costs.
