c6x | C6713- Momory Allocation Probolem

Hi,

I have been trying to save over 50,000 data points in run time and then transfer
them to a text file. When I am running my code for 25,000 data points, it's
running fine but giving so many errors as given below when I increase the size
of buffer to 51200. I really don't know what does it mean.

Build Complete,
28 Errors, 0 Warnings, 0 Remarks.

Will some one please help me out with issue ? How can I save larger data values
? How much is the limit for C6713 ?

I will appreciate your help.

The error message indicates [1] that you are out of memory and [2] that
you are trying to use the DSP's internal memory.

The problem is that [1] the memory map is not correctly setup for the
6713 OR [2] you need to put your data into external memory.

B.S.

Those error messages are from the linker. Not from running the code.
It seems this is an excellent time for you to read the DSP architecture manual
for the chip you are using and read the information on the .cmd file for the linker.

They mean there is not enough room in the IRAM memory section.

You will probably have to move the data points table to external RAM.
BTW:
How much external RAM do you have implemented on your project?

BTW:
if you have the problem again, then please paste the .cmd file listing in your post.

I am also getting the message given below but when I remove the check from
"Enable Memory Maping" tab it solves the problem but I don't know why it some
time happens ?

Loader: One or more sections of your program falls into a memory region
that is not writable. These regions will not actually be written to the
target. Check your linker configuration and/or memory map.

Thanks.

B.S.

If your looking at the 6713 architecture manual (available for download at
TI.com) part number SPRS186L,pdf then you see, on page 16 the memory map and on
page 17 the various ways the 'IRAM' portion of the memory map can be allocated
as L2 cache+IRAM.

Your program, per the linker error messages is larger than the available IRAM.

I say again : Your program is TOO BIG for the size of the IRAM.

Does your development board have any external RAM implemented?

If yes, then modify the configuration file, using the config tool, and move the
data table to the external RAM. You will also have to modify the memory map,
via the config tool, to include the available external RAM.

If no, then you will have to implement some external RAM (via additional
hardware) and move the data table to the external RAM via the config tool.

BTW:
Turning the ""Enable Memory Maping" off is a bad idea as this stops the linker
from checking that the program will fit within the available RAM.

I would go a bit further than Richard and say that disabling the Linker's detection of memory fit is a "really bad
idea" which will lead to nothing but trouble, kind of like replacing a fuse with wire, disabling a smoke detector,
etc.

BS,

Like we said - your program is too large for your memory. The following
snippet from your .cmd file indicates that the initial BIOS
configuration "told" the compiler that you only have 0x40000 bytes of
internal memory.

If you would have configured for external memory, it would show up. Your
choices are [1]configure for external memory [if you have it] OR [2]
reduce your code to fit into internal memory.

/* MODULE MEM */
-stack 0x400
MEMORY {
IRAM : origin = 0x0, len = 0x40000
}

B.S.

One more thing I noticed in your .cmd file listing.

Your configuration did not leave any room for L2 cache.

When you use external RAM, your application will greatly benefit from some L2
cache. So you will want to modify the configuration to allow for L2 cache.
I would allow for 64K of L2 cache for the maximum benefit.

_____________________________________

B.S.

I see a few 'ooops' in the configuration area.

For instance....
the '.EXT_RAM' section does not exist.
however, 'SDRAM' does exist.
so your pragma should look like this:
$pragma DATA_SECTION(data_stats,"SDRAM")
unless you define a specific section in the configuration named '.EXT_RAM' that
is large enough to hold your complete data table.
If you do define a .EXT_RAM section, then the size of the SDRAM section must be
reduced by an equal amount and the starting address of each section adjusted so
the sections do not overlap.

Then, as I looked at the configuration settings, I noticed:

1) the 'heap' is in SDRAM, that is not a really good idea unless the
application needs lots of room in the heap.

2) the 'stack' section is in SDRAM, that is a very bad idea
because the stack is referenced OFTEN and there is a major execution speed
penalty for having it in any place other than IRAM.

3) The BIOS sections need to be 'fast' so should be in IRAM

4) The startup code is only executed once, so placing it in SDRAM is probably
ok, however; I would have left it in FLASH and executed it from FLASH.

5) You want interrupt servicing to be 'fast', so the interrupt service table
should be in IRAM.

6) The 'text' section is the actual executable code. so placing it in SDRAM is
a major execution speed penalty.

7) If your code is initially in FLASH, then the jump switch tables should
probably be left in FLASH. They are actually part of the executable code, but
their usage is minimal (for most programs).

8) The '.cinit' section is only referenced during the startup code execution, so
leaving it in FLASH is a very good idea. BTW this is initialization values for
the ram data. It will be 'gone' over a power cycle.

9) The '.const' section never changes and is rarely referenced, so leaving it in
FLASH is a good idea.

10) The '.data' section is your program variables that will be initialized
during the startup code execution. Since such variables are usually referenced
often, it is a good idea to have them in IRAM. (however, that actual
initialization values can be left in FLASH as they are only referenced once
during the startup code.

BTW:
the whole idea was to make your link work.
The only problem with your link was the data_stats being too large to fit into
the IRAM. If I were doing this, the only thing I would have moved is the
data_stats and left everything else in IRAM/FLASH. Note: there is a execution
speed penalty for items in FLASH and usually also for items in SDRAM.

BTW:
It looks like there is no definition of the FLASH area.
IMO that should be added, so certain sections can be left in the FLASH, rather
than (during the startup code) copied into xxRAM then copied again into their
final execution/data location.

BTW:
I'm not sure if the DSP you are using has any differentiation between 'far' and
'near' addresses, but if it does, then I would plan the memory layout to use
'near' addresses when executing code that is run often or needs to run fast.

BTW:
if you move all the executable code out of SDRAM, then you can improve the
definition of SDRAM to be only data rather than code/data.
