Microkernel architecture
- Spatial isolation of OS from drivers and applicaions
- Fine grained fault isolation
and recovery
- Message passing design for
modular, well formed systems
- Comprehensive multi-core support
- Asymmetric(AMP), symmetric (SMP) and bound multiprocessing (BMP)
- Guard pages at the end of each virtual stack to protect against stack overflow
POSIX Compliance
- Validation using PSE 54 test suite
- Supports a broad range of POSIX API specifications
Deterministic Performance
- Pre-emptive scheduler with choice of schduling methods
- Destributed priority inheritance
Adaptive Partitioning
- Redistribute unused cycles to optimize CPU loading
- Guarantee CPU cycles to critical processes without compromising system performance
High Availability
- Heartbeat for early fault detection
- High availability manager (HAM) to restart failed or unresponsive processes and services
- Intelligent restart and transparent reconnection
Protected Direct Memory Access (DMA)
- IOMMU/SMMU Manager leverages x86 VT-d or Arm� SMMU derivatives to protect against unauthorized DMA
- Configurable boundaries for access to bus devices
- Boundary oblation monitoring and management
Processor Support
- 64-bit support for the latest ARMv8 and x86-64 SoCs
- Continued 32-bit support for ARMv7 SoCs
