about Illegal Instruction error in process of IJG sample program running

about Illegal Instruction error in process of IJG sample program running

Nice to meet you.

I have a question about using ipp5.0 under vs2005 complier.

The Ipp file name that we are using is w_ipp_pca_wmmx_p_5.0.2.001.exe.

Unfortunately, I don't have enough information about this file. But I guess this Ipp file may be used for a wireless device composed of pca processor.

After setting up this Ipp file, I got the sample program from this site.

As you know, that is IJG sample program for Ipp5.0.

My programming environment is below:

- Visual studio 2005(pocket pc 2003 ARMV4 emulator,)
- PC: intel pentium processor 2.13GHz

The error message is below:

Unhandled exception at 0x000f13f8 in jpeg_ipp50.exe: 0xC000001D: Illegal Instruction.

I found where an error occurred as below:

status = ippiDecodeHuffman8x8_Direct_JPEG_1u16s_C1(
00024E38 ldr r3, [sp, #0x48]
00024E3C add r3, r3, #0x59, 28
00024E40 ldr r3, [r3]
00024E44 str r3, [sp, #0x10]
an omission of several asm-instructions.

000F130C ldr r4, [sp, #0x24]
000F1310 ldr r5, [sp, #0x28]
000F1314 ldr r6, [sp, #0x2C]
an omission of several asm-instructions.
000F13E4 str r12, [r10], #4
000F13E8 subs r11, r11, #0x20

000F13F0 ldr r1, [r1]
000F13F4 ldr r4, [r4]
000F13F8 ldc p1, c0, [r5] => At this point, the error occurred

Please let me know why such problems take place.
