PostForum: Ask a Question   Posted: Thu Jun 25, 2015 8:43 pm   Subject: MMU,TLB and virtual memory
Hi,
I am modeling the ARM Cortex A9 MPx2 processor on the ZYNQ ZC702 board. I wanted to model the MMU,virtual memory and TLB.
So, could someone tell me where I should begin??? I did not understand ...

By algorithmic parameters I mean the parameters that affect the algorithm performance. Like I had mentioned in other posts about cache miss rate, execution time etc. Are there any other???:)

Hi,
Can I model an instruction cache as virtually tagged physically indexed and data cache as physically tagged and physically indexed??
How do I change the tagging and indexing?? Is it possible??

Hi,
I wanted to mention that I did not get the OVP sim finished message after simulation. I believe it got stuck after printing out the matrix

Yes, it is the same platform that provided the statistics earlier. I just changed the .elf file.
Thanks.
And I will try the steps that you have mentioned.:)

Hi,
I ran the binary file i.e. the .elf file obtained from Xilinx SDK on OVPSim.
I am getting the program to run. But it stops midway.
For example if I run the 20X20 matrix multiplication program ...

I am loading the .c file containing the application code(which I have given in the above thread)onto the board using the debugger in Xilinx SDK.
Yes, the Xilinx SDK does generate its own elf file.

Mr DuncGrah,
I am getting the output in Xilinx SDK itself and am running the same on Xilinx SDK.
As far as the binary is concerned, I am running the file obtained by compilation in Xilinx SDK on the ...

#include <stdio>
int main()
{
int m=35;
int n=35;
int p=35;
int q=35;

I am also hoping the same for instruction count. Is there a way by which I can measure the number of instructions that are executed for the application code alone( when running on the given processor) ...

By execution time, I mean is there a way by which I can measure the execution time of the application on the processor model. Excluding the execution time of the model platform simulation.
I want to ...
