DSP: BF531 V0.5

VisualDSP++ 5.0 Update 9.1

RTOS: VDK

In my project must use a test data buffer.

 

const short reverse_tab[] =
{
0x0,0x200,0x100,0x300,0x80,0x280,0x180,0x380,
0x40,0x240,0x140,0x340,0xc0,0x2c0,0x1c0,0x3c0,
0x20,0x220,0x120,0x320,0xa0,0x2a0,0x1a0,0x3a0,
0x60,0x260,0x160,0x360,0xe0,0x2e0,0x1e0,0x3e0,
0x10,0x210,0x110,0x310,0x90,0x290,0x190,0x390,
0x50,0x250,0x150,0x350,0xd0,0x2d0,0x1d0,0x3d0,
0x30,0x230,0x130,0x330,0xb0,0x2b0,0x1b0,0x3b0,
.......................
}

 

the memory watch:

Lost the 32 bytes at the begin.

I tested the same code using "Standard application"(No VDK), it's ok.

 

Why & How to do?
