Estimation of Memory Size from Memory Usage

Hello  DSPC 

Thank you for your support.

Can we estimate necessary RAM size of Hardware from "memory usage" of AWE modules?

It is useful  if we can , to decide the hardware (which DSP we use,,,)

We've understood the <nnn>_HeapSize.h is also useful.

Hello M.S.,

Yes, this is the correct way to determine the minimum amount of memory needed to run the AWD.  In the AWE Designer toolbar: Tools > Generate Target Files > [BaseName]_HeapSize.h.

Thanks,

Kevin

Hello, Kevin

Thank you for your prompt reply.

How about the size of awb (==Core0_InitCommands_Len)), dose it also effect the amount of memory(RAM) size?

My understandings are 

(1) "Memory usage"  of each AWE module  which we can see in the AWE Designer Canvas  includes the heap and code size.

(2) the total RAM size are the sum of the size of the heap ([BaseName]_HeapSize.h) ,  "Core0_InitCommands_Len ",  the size of  BSP which we create  and  Audio Weaver size.

Are my understandings correct?

Now still my understanding are not clear.. Could you help me?

The necessary memory size  (program and data)  is as follows?

[data]:   size of heap ( defined in [BaseName]_HeapSize.h.) .

                Dose it  include " Core0_InitCommands_Len = sizeof(Core0_InitCommands) / sizeof(int)" ?  Or 

                we need more data memory  for "Core0_InitCommands" table?

[program] : size of (BSP  +  AWE Core)

Best Regards,

Hello M.S.,

Sorry for my delayed response.  Your basic statements about data and program memory consumption are correct, but to answer your question, the c-array that you mention is not included in the heap memory requirements.  The c-array or .awb (audio weaver binary) file occupies its own memory.

Also, the size of memory that the AWE Core library can be truncated by only linking in the modules that your application needs, using ModuleList.h (additional info here).

Thanks,

Kevin

Hi,  Kevin

Thank you very much, I can understand it well.
