  • Can we use PMU(Performance Measuring Unit) on Cortex A8 for calculating cycles on Simulator without hardware?

    ARMv7A family members will have PMU on the processor. Using this PMU, we can access cycle counts. Can we relay on this using the simulator?

  • De-merits in using Cortex A9 for single core processor

    Hi Experts,

    A8 is meant for single core and A9 is for multi-core based.

    Consider in case of SoC is build with single core of A9 and A8 how we could compare both in terms of some metrics/parameters like power/speed ?

  • code compile using -mcpu for ARM platform

    When using gcc to compile c code for ARM platform, we set object platform by using:

         -mcpu = xxxxxx

    To what extent will that affect results of compiling ?

    For example:

         -mcpu = cortex-a8

    and

         -mcpu = cortex…

  • ARM Context ID Register & Process Context Switch

    Hi, all

    What is the content of Context ID Register of ARM Cortex A9. Is it OS that is responsible for assigning the value

    of Process ID and ASID? As far as I know, it is so in Linux. Is that the same in the other OSes?

    Is it essential to deal with ASID if…

  • Feature wise comparision for Cortex A series processors

    Hi Experts,

    Is there any document on feature wise comparison chart on the Cortex A series of processors ?

    Like,

    Cache for Cortex A8/9/52...

    MMU for cortex A8/9/52..

  • A Walk Through the Cortex-A Mobile Roadmap

    Chinese Version中文版

    Introduction

    The ARM Cortex-A mobile application processor product line spans several generations and three main product tiers. Developers and SoC designers experienced with one or more of the newer ARM ARM Processors benefit from an…

  • ARMv7-A - Power to the People

    Recently, I wrote an article called “Navigating the Cortex Maze” (Navigating the Cortex Maze) That was intended as an easy way-in to the ARM processor range, covering Cortex-A (architecture ARMv7-A), Cortex-R (ARMv7-R) and Cortex-M (ARMv7…
