velOSity INTEGRITY
Royalty-Free Real-Time Operating System
Features
Description
Product Information velOSity operating system designed high performance real-time systems where minimizing code size crucial. code been carefully tuned that core functions kernel small possible. addition, velOSity system calls implemented library callable subroutines. This provides automatic scalability: designers maximize performance minimize space requirements selecting embedding only those RTOS services that they need their application. INTEGRITY which provides memory-protected superset facilities offered velOSity, targets mission-critical real-time applications that emphasize reliability, security testability. INTEGRITY leverages memory management facilities hardware MMU's provide secure, memory protected environment. addition, scheduler true real-time scheduler, supporting multiple priority levels with guaranteed percentage allocations with level. most time critical processes permitted bypass protective layer, thereby eliminating overhead segmentation argument checking letting process directly kernel mode. Normal interrupts managed kernel, very time critical interrupts configured bypass kernel completely trap directly supplied interrupt service routines. Both RTOSs sport modern design, based latest thinking operating systems. Careful attention been paid keep current with state modern technologies: velOSity INTEGRITY have been optimized especially with today's high performance microprocessors memories. Integrated Debugging
