TalkThru

I'm doing tests with hardware "ADSP-21262 EZ-KIT LITE" and the software as "Block Based TalkThru (C)".
I put in the function "BlockProcess" my algorithm. But I see that output from the algorithm introduced me take effect only on 2 / 3 of the output signal. I also annoying peak (spurious effect) between a block and another.

Can not understand where is the anomaly.

Can you help

Hi,

I fixed this bug three years ago - thus don't remember exactly where it
was. The reason is related to incorrect block switching A->B->C. Please
compare the code segment from InitSport() function you have with the one
I send below.

void InitSPORT()
{
TCB_Block_C[0] = (int) TCB_Block_A + 3 - OFFSET + PCI ;
TCB_Block_A[3] = (unsigned int) Block_A - OFFSET; //adress pointer
to next TCB cpsp

//Proceed from Block B to Block A

TCB_Block_A[0] = (int) TCB_Block_B + 3 - OFFSET + PCI ;
TCB_Block_B[3] = (unsigned int) Block_B - OFFSET;

//Proceed from Block C to Block B
TCB_Block_B[0] = (int) TCB_Block_C + 3 - OFFSET + PCI ;
TCB_Block_C[3] = (unsigned int) Block_C - OFFSET;

....

Good luck,
