Algorithm 1. Pseudo-code for migration of the data by iDMA during object tracking

f r a m e_{n u m b e r}

= 0;

I n d e x_{p i n g P o n g B u f f e r}

= 0;

p i n g P o n g B u f f e r

[2];
Read first frame to

p i n g P o n g B u f f e r

[

I n d e x_{p i n g P o n g B u f f e r}

];
Transfer Ping buffer (

p i n g P o n g B u f f e r

[0]) to DRAM;
Wait for data transmission to end;
Change to Pong buffer by

I n d e x_{p i n g P o n g B u f f e r}

^ = 1;
foreach

f r a m e_{n u m b e r}

f r a m e A r r a y [t o t a l S i z e]

do
Read next frame to Pong buffer:

p i n g P o n g B u f f e r

[

I n d e x_{p i n g P o n g B u f f e r}

];
if (

f r a m e_{n u m b e r}

is not first frame){
Detect new object with trained template parameters.
Update object position and template parameters.
}
Transfer Pong buffer (

p i n g P o n g B u f f e r

[1]) to DRAM;
Train filter;
Wait for data transmission to end;
Change to Ping buffer by

I n d e x_{p i n g P o n g B u f f e r}

^ = 1;
