INtime RTOS is a deterministic, real-time operating system that runs on multi-core PC hosts. It allows critical real-time applications to run alongside Windows applications by explicitly partitioning host resources like cores and memory. INtime RTOS provides object-based services and communication between processes across nodes through its IPC mechanism. Solutions built on INtime RTOS can be deployed either on the same host as Windows or on distributed hosts.

Windows 8 introduces three types of apps: desktop apps, Windows Store apps, and Phone 8 apps. Windows Store apps are built on the new WinRT API and can be developed using HTML5, JavaScript and CSS, or managed languages like C++, C#, and VB. They integrate with the OS using contracts and metadata and run in a sandboxed environment. Desktop apps continue to use existing languages like C++ and .NET but only run on x86/x64. Phone 8 apps use Silverlight and run on the phone version of the Windows core.
The key problematic instructions for virtualization on ARM are those that change processor state or mode, access privileged resources, or cause unpredictable behavior when executed in user mode. These must be trapped and emulated by the virtual machine monitor.

Microkernel-based operating system developmentSenko Rašić
The document discusses microkernel-based operating system development. It describes how a microkernel has minimal functionality and moves drivers and services to user-level processes that communicate through inter-process communication calls. This can impact performance. Mainstream systems now take a hybrid approach. The document then describes the L4 microkernel and its implementation, Hasenpfeffer, which maximizes reuse of open source components. It lists components and features of the Hasenpfeffer system, including programming languages, drivers, and tools for development.
This document summarizes a lecture on microkernel design. It discusses the principles of minimality in microkernel design and how this leads to user-level services rather than services inside the kernel. It also discusses the mechanisms provided by microkernels, including abstracting memory as address spaces, execution as threads/activations, and interrupts/exceptions. A key mechanism is inter-process communication (IPC) which it discusses designs for, including synchronous IPC, asynchronous notifications, and IPC addressing schemes.

The Ultimate List of Opensource Software for #docker #decentralized #selfhost...Panagiotis Galinos
A list and description for interesting open source software for
#docker #decentralized #selfhosted #privacy #security
It has a description and an indicative image for each one.
Embedded systems developers can reduce costs by consolidating multiple systems onto a single multicore processor hardware platform. Each CPU core can be dedicated to a real-time task, such as motion control or vision processing. This allows real-time and general-purpose operating systems to coexist on individual cores without performance penalties. A virtualization-enabled real-time OS is needed to provide hardware-enforced isolation between OS environments on different cores. Using virtual devices and shared memory, applications can then communicate across OS environments with low interrupt latency comparable to a single-core system.

Operating Systems 1 (4/12) - Architectures (Windows)Peter Tröger
The Windows operating system was developed to meet requirements for a 32-bit, preemptive, virtual memory OS that could run on multiple hardware architectures and scales well on multiprocessing systems. It was designed to be extensible, portable, dependable, compatible with older systems, and high performing. The Windows kernel implements low-level processor-dependent functions and services like threading, interrupts, and synchronization. Device drivers translate I/O calls to hardware-specific requests using kernel and HAL functions. The HAL abstracts platform-specific details and presents a uniform I/O interface.

1. Consolidation of numerous workloads using partitioned multi-
core PC hosts, known as “Embedded Virtualization,” reduces
system costs and complexity by merging different application
types onto the same host.
In a heterogeneous deployment with an SMP OS, INtime RTOS
runs in parallel with Windows* (32-bit and 64-bit) to utilize
the extensive human machine interfaces (HMI) available on
Windows. The system services extend support to multiple hosts,
allowing creation of interoperable, distributed, real-time
systems with flexible deployment models.
As an AMP architecture, each node (core) runs an independent
instance of INtime RTOS, with its explicit hardware partition—
including dedicated core, memory, I/O, and interrupts. This
approach is optimal for security, reliability, and determinism,
when critical response time is important. All INtime RTOS and
Windows processes run natively, with support for all versions of
Windows—even Windows 10 (Figure 1).
Binary code developed for INtime RTOS remains forward com-
patible with the current INtime RTOS, preserving your software
development investment. Migration libraries are provided for
Windows API legacy RT extension code.

RTOS is a deterministic hard real-time dynamic operating system for Asymmetric
Multi-Processing (AMP) on multi-core x86-compatible processors. Unlike a hypervisor, a device driver,
or an application, INtime RTOS is a full operating system, complete with system services and capabilities
that developers expect to see in modern operating systems to enable fast and efficient development of
high-performance solutions. Capabilities include dynamic control of processes on multiple nodes (cores)
on multiple hosts, and rich inter-process communication (IPC) between all nodes of the system.

Data Sheet
2. INtime RTOS is a hard real-time event driven operating system
with determinism measured in microseconds.
Deterministic applications require dedicated and isolated
resources from the host: cores, memory, and I/O. INtime RTOS
was designed around deterministic applications and dedicates
resources to each real-time node by explicitly partitioning the
host hardware, giving the real-time application the needed
resources (Figure 2). INtime RTOS is built for embedded
virtualization deployments and it natively supplies a rich set
of services and capabilities that developers expect in a mature
operating system.
Drivers for low latency are included for:
• Ethernet and INtime’s High Performance Ethernet (HPE),
a foundation for EtherCAT*, Sercos III*, Profinet*
• xHCI USB, PCI*/PCIe*, and serial ports

Connectivity Standard Ethernet and TCP/IP stacks, including INtime’s High Performance Ethernet
IPC Mechanism GOBSnet, an INtime RTOS comprehensive IPC
To accelerate time to market and simplify development,
INtime RTOS provides the standard services of general
purpose operating systems. These services allow program-
mers to rely on the OS to manage the many system tasks
in their solutions without having to create their own code.
INtime RTOS is object based, supporting a familiar program-
ming methodology. The INtime RTOS kernel provides several
objects and maintains the data structures that define them
and their related system calls. For any created object, the
kernel returns a handle for that object, which can be used in
any INtime RTOS or Windows process across the distributed
system. Each process executes in protected user mode (Ring 3),
with up to 4GB physical memory, limited only by host resources.

Embedded virtualization through explicit hardware partitioning
INtime RTOS provides a deterministic IPC mechanism
(GOBSnet) to catalog, search, and use all created objects
across the system, enabling scalability for embedded system
design (Figure 3).
Using explicit hardware partitioning and asymmetric multi-
processing (AMP or core affinity), INtime RTOS enables
scalability of deterministic applications across multiple
nodes for performance or combined on fewer nodes for
cost savings.
GOBSnet delivers a comprehensive set of efficient commu-
nication services across Windows and real-time applications,
whether running on the same multi-core host or across
distributed hosts. Though isolated from each other, sharing
across environments allows Windows services to interact with
embedded functions, enabling integration and eliminating
the inter-networking complexity and points of failure risks of
traditional embedded designs. This provides flexibility to
scale with the potentially changing topology of the solution
without porting.

INtime RTOS enables a modular programming model running
user-mode applications instead of kernel mode driver extensions.
Support for global objects, multiple IPC mechanisms, full
exception and error handling, and a rich set of standard kernel
services allows developers to quickly and easily create scalable
and reliable embedded applications.
TenAsys supports INtime RTOS solution development with a wide
range of tools, including INtime Software Development Kit (SDK),
which integrates into the familiar Microsoft Visual Studio environ-
ment to accelerate solution creation.
INtime RTOS summary

The Distributed Systems Manager (DSM) monitors all nodes
and their processes to maintain continuity and availability of
the entire embedded system. The DSM tracks the state of the
system, monitors the health of its components, and cleans up
in the event of component termination or failure.
Each instance of INtime RTOS or Windows is considered a node.
Any INtime node can create objects accessible from any node,
whether on a single host or across a system of distributed hosts.
An advanced integrated memory manager maintains memory
allocation for each process.
