DynamIQ

What is DynamIQ?

Arm DynamIQ is a cutting-edge multicore processing architecture that redefines how processors manage performance and efficiency. Unlike traditional big.LITTLE configurations, DynamIQ allows multiple core types—ranging from high-performance to power-efficient cores—to coexist within a single cluster. This design enables more flexible and scalable solutions across various applications, from smartphones and wearables to automotive systems and edge computing devices.

Key Features of DynamIQ

• Single Cluster Integration: DynamIQ supports up to eight heterogeneous cores in a single cluster, facilitating configurations like 1+7, 2+6, or 4+4. This integration reduces latency and enhances communication between cores.
• Advanced Memory Subsystem: The architecture introduces a shared Level 3 (L3) cache, which is configurable up to 4MB. This shared memory pool improves data access speeds and reduces memory latency across cores.
• Enhanced Power Management: DynamIQ features intelligent power management with fine-grained control over CPU speeds and rapid transitions between power states (on/sleep/off), leading to significant energy savings.
• AI and ML Optimization: The architecture includes dedicated instructions for machine learning and artificial intelligence tasks, offering up to a 50x performance improvement over previous systems.
• Safety and Reliability: For automotive and industrial applications, DynamIQ supports Arm’s Automotive Enhanced (AE) CPUs, enabling compliance with safety standards like ISO 26262 ASIL D and IEC 61508 SIL 3.

How to Use DynamIQ

Implementing DynamIQ technology involves selecting compatible Arm CPU cores, such as the Cortex-A75 and Cortex-A55, and integrating them into your system-on-chip (SoC) design. The DynamIQ Shared Unit (DSU) plays a crucial role in managing communication between cores and the memory subsystem. Developers can leverage Arm’s Energy Aware Scheduling (EAS) to optimize task allocation across cores, ensuring efficient power consumption and performance.

Pricing and Licensing

Arm operates on a licensing model that includes an upfront fee and a royalty based on the number of chips sold. The exact pricing varies depending on the specific cores and features licensed. For detailed pricing information, it’s recommended to contact Arm directly or consult with an authorized Arm partner.

Frequently Asked Questions (FAQs)

• What CPUs are compatible with DynamIQ? DynamIQ is compatible with Arm Cortex-A75 and Cortex-A55 CPUs, as well as their successors that support the Armv8.2-A architecture.
• Can DynamIQ be used in existing big.LITTLE systems? No, DynamIQ requires a complete redesign of the CPU cluster and is not backward-compatible with older big.LITTLE configurations.
• What are the benefits of the shared L3 cache? The shared L3 cache reduces memory latency and allows for more efficient data sharing between cores, enhancing overall system performance.
• Is DynamIQ suitable for safety-critical applications? Yes, with the AE variants of the DynamIQ Shared Unit, it supports safety standards like ISO 26262 ASIL D, making it ideal for automotive and industrial applications.
