CPU Performance on OMAP5

Ishaqe Ahamed

Hi

Is any performance evaluation was done on OMAP5 ARM Cortex-A15 cores In Linux ?
What is the maximum frequency which can be set for each ARM Cortex-A15  core in Latest OMAP5 GLSDK 6.04.00.02 release ?

Regards,

Ishaqe

    Hello Ishaqe,

    The maximum frequency supported by Cortex A15 MPU in OMAP5 depends on the Operating Performance Point.

    OMAP5 supports four Operating Performance Points (OPP)

    OPP_LOW_MPU

    OPP_NOM_MPU

    OPP_HIGH_MPU

    OPP_SPEEDBIN_MPU

    The highest clock frequency for MPU is 1699.2MHz at OPP_SPEEDBIN_MPU.

    OPP_SPEEDBIN_MPU operating point provides a higher guaranteed frequency in OPP_HIGH_MPU mode by performing binning during production test for the MPU. This operating point will only be available with some orderable part codes. For more information, please, contact your T.I. representatives

    I think that in OMAP5 GLSDK 6.04.00.02, the MPU subsystem is clocked by 1500MHz.

    For more information refer to OMAP5 Operating Condition Addendum - http://www.tij.co.jp/jp/lit/ug/swpu329/swpu329.pdf

    Best regards,
