Real-Time Computing at the Edge
A major transformation towards software-defined solutions is happening at the edge. It's driven by factors such as the need for flexibility and scalability, changes in the workforce, and more. A key element of this transformation is the need to support real-time workloads along with best-effort workloads on the same system.
Platforms enabled with Intel® Time Coordinated Computing (Intel® TCC) deliver optimized compute and time performance for real-time applications, which include support for IEEE* 802.1 Time Sensitive Networking (TSN) over wireless and wired converged networks.
Frequently Asked Questions
The term “real-time system” refers to hardware and software components that perform real-time application functions and can respond to events within predictable and specific time constraints.
Real-time systems are classified as soft real-time or hard real-time. A soft real-time classification means the system continues to function even if it’s unable to run within an allotted time. Most importantly, if the system has missed its deadline, it does not result in dangerous consequences. A hard-real-time classification means the system ceases to function if a deadline is missed, which can result in catastrophic consequences.
Real-time systems are key pieces of technology, and as such, they are used in a variety of industries with applications spanning from process automation systems to warehousing to production assembly lines, agriculture, and healthcare.
Key Use Cases

Real-Time Audio & Video Processing
This technology provides bounded maximum latency for scheduled traffic through switched Ethernet networks.
TSN is a set of IEEE 802 standards that are defined by the IEEE TSN task group. These standards enable ultra-reliable and low-latency communication over Ethernet to support time-sensitive applications. TSN achieves this by using time synchronization, traffic scheduling, and network configuration.

White Paper: TSN From Theory to Implementation in Industrial Automation
- Time synchronization provides hardware capabilities that achieve precise time synchronization and eliminate the need for software-based synchronization and associated adverse effects caused by the operating system. Coordinate various clocks found in individual IP blocks, such as CPU, PCIe*, network, audio, and more.
- Timeliness provides hardware capabilities that support minimizing the latency of data packets from one IP block to another. Allocate critical resources, such as cache, for real-time applications. Prioritize I/O, such as PCIe traffic.
