On the SM1000 we also place constant tables in flash, so they won't be loaded into RAM. The SM1000 actually runs the full FreeDV stack - so there is a modem and FEC in there too, plus speech I/O drivers with large buffers. If you just want the speech codec, I'd guess < 64k run time RAM, although I haven't measured it stand alone. - David On 3/11/19 8:54 am, Don wrote: > The CPU on the SM1000 is an STM32F405 with 192k of SRAM. > > It will not hold a full Codec2 build with all of the modes enabled! > If you look at stm32/CMakeLists.txt in tge source you will see this: > > add_definitions(-DFREEDV_MODE_EN_DEFAULT=0 -DFREEDV_MODE_1600_EN=1 > -DFREEDV_MODE_700D_EN=1 -DCODEC2_MODE_EN_DEFAULT=0 -DCODEC2_MODE_1300_EN=1 > -DCODEC2_MODE_700C_EN=1) > > which disables all of the modes except 1600 and 700D. > > Don > > > On Sat, Nov 02, 2019 at 03:12:24PM -0700, Sam Shoja wrote: >> Dear Ammar, >> >> Codec2 in the project SM1000 is implemented on STM32F MCU family, which >> have between 96KB and 386KB of Ram and CPU clock of 96MHz to 180MHz. >> The question can be, does SM1000 have external RAM?
