question about the *.cfg file of JPEG2K Encoder on C66x

Hi, Sir

Excuse me, when I use the encoder lib : C66x_j2e_01_00_00_01_ELF, I have some question about the *.cfg file in the App.

After import the project in App, build completely. There build a *_pe66.c file from the *.cfg file. I find the following codes in *_pe66.c.

"

#define TCI6608
#include <ti/sdo/fc/edma3/edma3lld_cfg.h>


/* Configuration defined in edma3lld_cfg.h */
extern __FAR__ EDMA3_GblConfigParams
ti_sdo_fc_edma3_lld_globalConfigParams[GLOBAL_EDMA3_INSTANCES];

/* Set globalConfig to array declared above */
EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig =
(Void *)&ti_sdo_fc_edma3_lld_globalConfigParams;

/* Configuration defined in edma3lld_cfg.h */
extern __FAR__ EDMA3_InstanceInitConfig
ti_sdo_fc_edma3_lld_instInitConfig[GLOBAL_EDMA3_INSTANCES][NUM_REGION];

/* Set regionConfig to array declared above */
EDMA3_InstanceInitConfig * ti_sdo_fc_edma3_Settings_regionConfig =
&ti_sdo_fc_edma3_lld_instInitConfig[0][0];

"

When I rewrite the content in the cfg file of my new project(I make the new cfg file according to the *.cfg file in App), but my *_pe66.c only have:

"

EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig = NULL;
EDMA3_InstanceInitConfig * ti_sdo_fc_edma3_Settings_regionConfig = NULL;

"

Could you please tell me, how can I make my the *_pe66.c has the same content like the one from the App lib?

what's the key point in the *.cfg file?

    Hi Wang, as I can see the EDMA global configuration params is defined on Frame Components edma3lld_cfg.h file (C:\Program Files\Texas Instruments\framework_components_3_22_03_09\packages\ti\sdo\fc\edma3\edma3lld_cfg.h) . Could you please share the modifications you have done to the project?

    Thank you,

    Paula

    hi, Paula, thank you for answering my question.

    The words with underline is source code from project.

    The EDMA global configuration params below is defined in edma3lld_cfg.h.

    /* Configuration defined in edma3lld_cfg.h */
    extern __FAR__ EDMA3_InstanceInitConfig
    ti_sdo_fc_edma3_lld_instInitConfig[GLOBAL_EDMA3_INSTANCES][NUM_REGION];


    But, here is a point(showing below) is defined in the generated file *_pe66.c, which is generated from file *.cfg.

    EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig =
    (Void *)&ti_sdo_fc_edma3_lld_globalConfigParams;

    The above code is from the app in C66x_j2e_01_00_00_01_ELF lib.

    In my project, the generated file code is :

    EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig = NULL;

    My question is what is key point in the *.cfg, that can generated file *_pe66.c with code like:

    EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig =
    (Void *)&ti_sdo_fc_edma3_lld_globalConfigParams;

    hi, Paula。

    I also have another question.

    I see the following wrodes in alg_malloc.c file from C66x_j2e_01_00_00_01_ELF:

    /* !!! These data are hard coded sizes relative to algorithm values.
    Before starting to test Encoder, it is important to make sure that
    these values match with values defined in j2e_ti_def.h !!! */

    what is j2e_ti_def.h? where can I find it ?

    Hi Wang, j2e_ti_def.h is part of the the Library project, however, C66x_j2e_01_00_00_01_ELF published on the web doesn't include the source files for the codec library only the prebuild library (..\C6678_J2E_001\Lib\j2e_ti_c66.ae66). Quick question, what do you need to change in alg_malloc.c? also did you get resolved previous issue with .cfg? if not could you please share with us your project?

    thank you,

    Paula

    Hi, Paula.

    1\ what do you need to change in alg_malloc.c?

    When using the lib app, I fond the memory section of J2Ememtab1 must be placed in L2SRAM. If not, the process function will return error code 0x8031.
    Now I am using the lib on C6671, but the generated size of photo in different tests are different.

    Eg, I test a photo of 3296*2160 with format YUV_422P.

    First time the generated size is 5345318 byte, then I turned off. And after a while, I test again, but the generated size is 5345227 byte.
    I didn't know why they are different.

    Eg, I test a photo of 640*480 with format YUV_422P.

    The generated size of photo in different tests are the same, which is 53114 byte.

    so I doubt if I need to change the size of the buffers of J2Ememtab0~J2Ememtab5 in alg_malloc.c file.


    2\ the previous issue with .cfg?

    my .cfg file is like this.2045.rmva590prj.cfg

    But in the generated file, I see codes like:

    EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig = NULL;

    How can I get the code like:

    EDMA3_GblConfigParams * ti_sdo_fc_edma3_Settings_globalConfig =
    (Void *)&ti_sdo_fc_edma3_lld_globalConfigParams;

    Hi Wang,

    I was pointed out that EDMA3LLD doesn't support C6671 platform (http://software-dl.ti.com/dsps/dsps_public_sw/psp/edma3_lld/edma3-lld-bios6/02_11_11_13/exports/release_notes_edma3_lld.html)

    However, EDMA Resourse manager has a generic lib which can be used for any platform if the application supplies the EDMS "global configuration" and "region configuration" for the platform/application. An example of C6678 "global configuration" can be found at edma3_lld_02_11_05_02\packages\ti\sdo\edma3\rm\src\configs\edma3_c6678_cfg.c: EDMA3_RM_GblConfigParams edma3GblCfgParams [NUM_EDMA3_INSTANCES]. Similar array needs to be defined for C6671 according to C6671 spec, and then passed to FC along with region config before calling RMAN_init():

    EDMA3_PARAMS.globalConfig = (EDMA3_GblConfigParams *)&global_config[edmaInstanceId];

    EDMA3_PARAMS.regionConfig = (EDMA3_InstanceInitConfig *)&region_config[edmaInstanceId][coreId];

    >>>Inside Current J2E Testapplication>>>

    EDMA3_PARAMS.regionConfig = &C6608_config[1][DNUM];

    >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

    About your buffer question, I checked j2e_ti_def.h, below max image values:

    #define MAX_IMAGE_X 6600

    #define MAX_IMAGE_Y 4400

    #define MAX_DIM max(MAX_IMAGE_X,MAX_IMAGE_Y)

    so your image should fit. Quick question when you decode the image both/neither/one decode ok?

    thank you,

    Paula
