FEXER OX guarantees security with full virtualization in today’s Connected world
Security and reliability are critical for connected devices and embedded systems in IoT (Internet of Things) era.
SELTECH’s FEXER OX directly interact with CPU core and enables multi OS systems operation in secure and independent manner in fully virtualized environment.
With this methodology, for instance, in system firmware update where security risks are high, access to personal information, device system control information, and proprietary information are fully controlled and securely protected. It improves system reliability.
This functionality can be fully achieved with 32K Byte, extremely compact memory footprint. And it uses only 1% of CPU power, extremely light design. These benefits bring users flexible choices for CPU’s and platforms.
FEXER OX hypervisor also helps customers optimize TCO (Total Cost of Ownership) in migration from distributed microcontrollers usage to SoC integration.
FEXER OX is Fastest, Lightest and Shortest
Bare-metal hypervisor (Type I)
Fully optimized for embedded systems, completely different from other hypervisors developed from virtualization technology for PC/Server
Highly abstraction design – overhead minimization for;
Inter-OS communications, System calls, context switches increases, in read/write in different memory area by virtualized I/O’s
Lightest and Fastest
Foot print 32K Byte
99% is available for CPU power (tested in LMBench)
Flexible choices for major platforms
MIPS, ARM, Intel architecture, PowerPC, SH, FPGA, etc.
Multi-core, Single-core (support both SMP and AMP)
Rich OS’s (Linux, Android, Windows)
Rich OS and RTOS (Real-time OS): multi-OS combination
Non-Secure mode and Secure-mode switching by utilizing MIPS full-virtualization VZ and ARM TrustZone
Controls and protects from threats for Rich OS’s environment
Global standard compliant
Fully compliant with Global Platform Enabling Secure OS
Hardware level full virtualization, independent operation utilizing MIPS full-virtualization VZ technology (support M5150 and I6400 cores)
Process and hardware resource virtualization utilizing ARM TrustZone
Secure interface using Global Platform standard TEE (Trusted Execution Environment)
OS porting needs no modification or slight modification only (normally no modification)
Users take advantage of OS/platform providers technical support
Shortest turnaround for porting and verification
“ FEXEROX ” use case examples eight Multiple-OS
Consolidating multiple ECPU in a Vehicle SoCs
BoM cost reduction also induce assembly cost and weight reduction thus improves in fuel consumption.
Improvement in manufacturing efficiency and a development cost because ECU change for every shipping destination is unnecessary. Only SW changes on the same SoC are necessary.
#Using Multi-chip configuration
You can continue using the conventional development process
Complex in sharing peripherals and data exchanges
Separate RichOS (Linux etc.) monitoring is necessary
#Using Hypervisor (FEXEROX) configuration
Easy in sharing peripherals and data exchanges
Each RTOS(ECU) operates independently
RTOS operate independently even if RichOS (Linux etc.) operation is unstable
Hypervisor can monitor and reboot RichOS
MIPS VZ and ARM TrustZone are available to access and control peripherals
Installation of Hypervisor necessary (RTOS SW heritage reusable)
Use FEXEROX as a “Secure OS”
Supports two secure frameworks, MIPS VZ and ARM TrustZone
Provide CAN protection for Infotainment and networking
Read only operation for CAN mileage and fuel consumption data access from related applications
Can hide RMP key for Digital terrestrial broadcasting and Miracast HDCP key
RTOS can handle the rest of protection needs using appropriate secure framework
Co-existence of RichOS & RTOS for Vehicle applications
Fast start-up of Linux/Android by parallel execution of Kernel
Image Extraction and device initialization
Fast start-up operations of Back Camera, Logo animation, Music play using RTOS
User can use OS unconsciously
Secure full graphical meter for Vehicle applications
Safe graphical meter control using RTOS while Infotainment control using RichOS
Meter operation secured even if Linux crashed
ISO26262 certification using RTOS with small code size
