ADSP- 2189M

Hi  ,

Has anybody come across this DSP device. I cannot find much material on the internet. For example any example source codes. I have a project GPS module date is coming wrong as an input to this DSP device. The DSP device needs to be programed to correct this date. Date is coming as 22/12/2019 it needs to be corrected to be current date.  Also, there is GPS weeks rollover every 1024 weeks. I need to write it in Assembly language. Is there way to this.
