7. Extensions and improvements
- makes some extensions and improvements on the basis of the standard profile of the ITRON4.0 specification
- takes the part of Protection Extension of ITRON4.0 Specification ( ITRON4.0/PX specification)
- follows TOPPERS Standard Interrupt Processing Model
Strict standardization will produce extra costs. To avoid this,ITRON specification employed loose standardization for interrupt processing. However, it has been 8 years since the publication of μITRON4.0 and the software environment has changed a lot. Now a little extra expense is acceptable in order to enhance the efficiency.
In this background, TOPPERS project establishes TOPPERS Standard Interrupt Processing Model, which is different from ITRON specification for good reusability. So interrupt processing applications can be constructed on ASP kernel without detailed knowledge of the interrupt processing architecture of processors.
