ASTRI ARM9E ITU-T CPT encoder
is optimized for the ARM9E architecture. The performance
is depended on several factors of the target ARM9E
platform: |
| • |
I-Cache size |
| • |
D-Cache size |
| • |
SDRAM speed |
| • |
Availability of TCM |
|
| Please make enquires on the performance
for a specific ARM9E platform. |
