adsp-21565 insufficient memory is indicated when integrating third-party algorithms

Hi, could you please confirm are you using SigmaStudio or SigmaStudio+?

sigma studio ,version4.7

Thank you. The SigmaStudio for SHARC memory block allocations are taking place in the file "adi_ss_app.ldf" which is included in "app.ldf". You can change the SS4G_block2 with other physical memory block to "mem_block0_bw" or "mem_block1_bw" for adjusting the memory block to fit for your parameter memory requirement. For example,

/*
** SigmaStudio for Griffin application linker description file for GMAP
*/

/* Default for SSn code */
SS4G_block0
{
RESERVE(_Block0_L1_space, _Block0_L1_space_length = 2, 2)
RESERVE_EXPAND(_Block0_L1_space, _Block0_L1_space_length, 0, 2)
} > mem_block0_bw

/* Default for SSn data */
SS4G_block1
{
RESERVE(_Block1_L1_space, _Block1_L1_space_length = 2, 2)
RESERVE_EXPAND(_Block1_L1_space, _Block1_L1_space_length, 0, 2)
} > mem_block2_bw

/* Default for SSn parameter */
SS4G_block2
{
RESERVE(_Block2_L1_space, _Block2_L1_space_length = 8, 8)
RESERVE_EXPAND(_Block2_L1_space, _Block2_L1_space_length, 0, 8)
} > mem_block1_bw

SigmaStudio internal framework also will reserve some additional memory which wont shown in the Memory information of SigmaStudio project compilation. So try changing the memory blocks as shown. If parameters not fit with any other memory blocks, then you need change the 3 rd party algorithm to use application allocated memory in the algorithm(applicabale if algorithm have read only data like coefficients), since the parameter data can't be split to different memory blocks. 

Thanks.

Hi,Sakthivel P.

Thanks for your reply.

 Q1:I modified the ldf file as you did, but still Allocation failed! Insufficient memory;Is there any other way besides modify the 3rd party algorithm?

SigmaStudio internal framework also will reserve some additional memory which wont shown in the Memory information of SigmaStudio project compilation.

Q2:----What is the memory size of this part? Can you tell me the general range? Or random size?

Thanks.

Please refer the processor data sheet for memory range.
Since you are having 3 party algorithm its difficult to guess what the required memory. Please contact your regional FAE's for further help.
