Possible allocatable RAM memory for A53 mode

Alan Xie over 2 years ago

Hi,

I'm trying to emulate my program on A53 FVP, where there's a need to malloc ~64G size of data. Therefore I'm wondering：

- What is the mechanism of allocating RAM space for FVP device? Is it using system RAM (where my development studio is running) or it is using modeled RAM from server

- How many RAM memories are available for A53 model?

Hi Alan

The RAM used by the FVP model comes from the system RAM on the machine where your Arm DS is running.

The memory map of Base Platform models, such as as the FVP_Base_Cortex-A53x1, is documented at
developer.arm.com/.../Base-Platform-memory-map

Hope this helps
