Intel real-time technology supports new solutions that require a high degree of coordination, both within and across networked devices. Intel® Time Coordinated Computing (Intel® TCC)-enabled processors deliver optimal compute and time performance for real-time applications 1. Using integrated or discrete Ethernet controllers featuring IEEE 802.1 Time Sensitive Networking (TSN), these processors can power complex real-time systems.

Enable Real-Time Use Cases

Intel IoT real-time computing performance and solutions are focused on hard real-time use cases where missing a deadline is a system failure. Hard real-time is necessary in areas such as robotics, automotive, and utilities where a capability fails if it cannot be executed within the allotted time span (deadline).

Real-time offerings from Intel support new solutions that deliver both high-compute & real-time performance by:

  • Prioritizing real-time workloads access to cache, memory, and networking
  • Minimizing disruption from other workloads
  • Optimizing performance for both real-time and non-real-time workloads
  • Ensuring availability in both native and virtualized environments

Real-Time Performance

Intel® TCC and TSN

 

Intel® TCC Time Synchronization
Provides a hardware mechanism to coordinate the various clocks found in individual IP blocks.

Intel® TCC Timeliness
Provides a hardware mechanism to specify latency of data packets from one functional block to another.

T
ime-Sensitive Networking (TSN)

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.

Time-Sensitive Networking (TSN)

Time sensitive networking (TSN) refers to a collection of IEEE standards, specifications and capabilities based on standard Ethernet networks to support time-sensitive applications and supports precision time synchronization, timeliness for data delivery, and traffic scheduling.

 

Why TSN?

  • Secure and reliable delivery of data

  • Guaranteed latency for data delivery

  • Converged networks save operating costs

  • Simplifies system configuration and operation

  • Open ecosystem

 

Platform Features

  • 1-3 integrated Ethernet TSN controllers
  • Enable ultra-reliable low-latency communication (URLLC) machine-to-machine communication up to 2.5Gbps/port speeds
  • Supports coexistence of hard real-time operational technology (OT) and soft real-time information technology traffic in a single network, reducing infrastructure cost
  • Simplify board design with integrated Ethernet controllers; less power consumption, smaller form factor, bill of material cost saving
  • Streamline software development with open standard reference software

 

Supported Ethernet TSN standards

  • IEEE 802.1AS       Generalized Precision Time Protocol
  • IEEE 802.1Qbv    Time-aware Shaper
  • IEEE 802.1Qav    Credit-based Shaper
  • IEEE 802.1Qbu   Frame Preemption

Intel® Time Coordinated Computing (Intel® TCC)

Key Elements

  • Time Synchronization provides hardware capabilities to achieve precise time synchronization and eliminate the need for software-based synchronization and associated adverse effects caused by the OS. Coordinate various clocks found in individual IP blocks, such as CPU, PCIe, network, audio, and more.

  • Timeliness provides hardware capabilities that minimize 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.

Benefits of Intel® Time Coordinated Computing (Intel® TCC) and Intel® TCC Tools:

  • Enable reliable worst-case execution time (WCET) I/O within compute node.

  • Speed time to market and reduce total cost of ownership with simple tuning.

  • Easily scale from Intel Atom® x6000E Series processors (code named Elkhart Lake) and 11th Gen Intel® Core™ processors (code named Tiger Lake UP3) to next gen with Intel® TCC.

  • Maximize efficiency by aggregating time-critical and non-time-constrained applications onto a single board.

Intel® TCC Software Enabling

There is no “one size fits all” solution. After choosing the right Enhanced for IoT Intel processor, the steps below are a recommended sequence in which customers should apply various “tuning” capabilities that Intel offers as part of our real-time offering:

  • Leverage our Board Support Package (BSP) with real-time optimizations
  • Enable Intel® TCC Mode in BIOS
  • Utilize Intel® TCC Tools (coming soon) for the most granular real-time tuning or to balance between real-time performance, power consumption, and general compute performance
