what did these  Assembly codes mean?

Dear all,
i debugged my codes on AXD, and the microcontroller is arm7 s3c44b0.
it ran well at the beginning, into the "main" function, did some initializations, and so on.
and then it ran into the disassembly mode. the Assembly codes were below:

026ec27c [0x2e2e2e2e]   cdpcs    p14,0x2,c2,c14,c14,1
026ec280 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec284 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec288 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec28c [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec290 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec294 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec298 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec29c [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2a0 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2a4 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2a8 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2ac [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2b0 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^
026ec2b4 [0x69696969]   stmvsdb  r9!,{r0,r3,r5,r6,r8,r11,r13,r14}^

why this happened?according to these Assembly codes, can anybody tell me what was the microcontroller doing?
many thanks!
