Re: Possible reason for H.264 Encoding error

Hi Ashwin,

I am using a customised board from other vendor.

I am following the example from H264_MP_Encoder_Developer_Guide_Rel3.0.0 and it appeared to fail more frequently at zero degree.

CORECLK  600MHz

SYSCLK  100MHz

I forget to mentioned that I attempted to do a soft core and system reset when the encoding fail. Would like to also check does the follow reset codes do a reset of program counter or will it re-read the program from flash again?

.global system_reset, systemreset ;

systemreset:

/* Issue system soft reset */

P0.L = LO(SICA_SWRST) ;

P0.H = HI(SICA_SWRST) ;

R0.L = 0x0007 ;

W[P0] = R0 ;

SSYNC ;

/* *******************

Wait for system reset to complete (needs to be 5 SCLKs). Assuming a worst case CCLK:SCLK ratio (15:1), use 5*15 = 75 as the loop count.

P1 = 75 ;

LSETUP(start, end) LC0 = P1 ;

   start:

   end:

      NOP ;

/* Clear system soft reset */

R0.L = 0x0000 ;

W[P0] = R0 ;

SSYNC ;

/* Core reset - forces reboot */

RAISE 1 ;
