OpenCL memory banks

Hello, 

 

From the hello world example, I got: 

CL_DEVICE_GLOBAL_MEM_SIZE = 4294967296,  

which means 4GB global memory.  

I am using a nallatech 385a7 board, so why the global memory size I got from the example is not 8GB instead? (2banks of 4GB). Is it possible to use all the 8GB memory on board? 

 

Thanks.

Re: OpenCL memory banks

Hi, 

 

I would recommend upgrading the BSP to the latest available version which supports 8GB of global memory on the 385 A7. The current version is R001.003.0001 and was tested in Quartus-II 15.0.0.145. 

 

You should contact Nallatech directly with this form to obtain access to the latest BSP:
