[Speex-dev] alignment and static variable size question

[Michael Jacobson]

Hi,
 
I am using 1.2beta2 on a TI 54x, narrow band
 
I changed all the speex dynamic allocation variables to static ones. 
It seems to work ok but when minor things change in the project it all
goes to hell.  I was hoping somebody could:
 
a) verify that my sizes are correct or if they are too small
 
b) Tell me if anything in the speex library is supposed to be aligned
in any way in memory.  I see there is an ALIGN define in one of the
files for the stack but I am not entirely sure what that means (i'm
inexperienced in C).
 
here are all the sizes I use:
 
#define ENC_WINBUF_SIZE 40
 #define ENC_EXCBUF_SIZE 306
 #define ENC_SWBUF_SIZE 306
 #define ENC_LAGWINDOW_SIZE 11
 #define ENC_OLD_LSP_SIZE 10
 #define ENC_OLD_QLSP_SIZE 10
 #define ENC_MEM_SP_SIZE 20
 #define ENC_MEM_SW_SIZE 20
 #define ENC_SW_WHOLE_SIZE 20
 #define ENC_MEM_EXC_SIZE 20
 #define ENC_MEM_EXC2_SIZE 20
 #define ENC_PI_GAIN_SIZE 8
 #define ENC_PITCH_SIZE 4
 
 #define DEC_EXCBUF_SIZE 500
 #define DEC_INTERP_QLPC_SIZE 10
 #define DEC_OLD_QLSP_SIZE 10
 #define DEC_MEM_SP_SIZE 20
 #define DEC_PI_GAIN_SIZE 8
 
#define SPEEXENC_PERSIST_STACK_SIZE 5000
#define SPEEXENC_SCRATCH_STACK_SIZE 1170
#define SPEEXDEC_PERSIST_STACK_SIZE 2500
#define SPEEXDEC_SCRATCH_STACK_SIZE 550
 
Thank you
 
-Mike
