Component Specifications

Definition
The Inter-Core Communication Bus is a specialized electronic component within multi-core processors that facilitates high-speed, low-latency data exchange between individual processing cores. It employs advanced signaling protocols and arbitration mechanisms to manage simultaneous data transfers while maintaining data integrity and synchronization across the processor architecture.
Working Principle
Operates on packet-switched or circuit-switched protocols using dedicated physical pathways (traces) between cores. Implements arbitration logic to manage access conflicts, error correction codes for data integrity, and clock synchronization mechanisms to ensure coherent data exchange across asynchronous core operations.
Materials
Copper alloy traces (typically 99.9% pure copper with alloying elements for thermal stability), silicon dioxide insulation layers, gold-plated contact points for corrosion resistance, FR-4 or polyimide substrate material
Technical Parameters
  • Latency < 5 ns
  • Voltage 0.8-1.2V
  • Bandwidth Up to 512 GB/s
  • Protocol Support AXI, CHI, OCP, proprietary protocols
  • Signal Integrity BER < 10^-15
  • Power Consumption 3-15W depending on traffic
  • Operating Temperature -40°C to 125°C
Standards
ISO/IEC 11801, IEEE 802.3, JEDEC JESD204C, PCI-SIG PCIe 5.0

Frequently Asked Questions

What is the primary function of an Inter-Core Communication Bus?

The primary function is to enable efficient data sharing and synchronization between multiple processing cores within a single processor package, allowing parallel processing tasks to coordinate effectively.

How does bus arbitration work in multi-core systems?

Bus arbitration uses priority-based or round-robin algorithms to manage simultaneous access requests from multiple cores, ensuring fair access while minimizing latency through dedicated arbitration logic circuits.

What are the key performance metrics for evaluating bus efficiency?

Key metrics include bandwidth (data transfer rate), latency (time delay), power efficiency (watts per gigabyte), error rate, and scalability (ability to support additional cores).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
