Arm Cortex-M55 Processor

The new Arm Cortex-M55 processor brings endpoint artificial intelligence (AI) to billions. It’s Arm’s most AI-capable Cortex-M processor and the first to feature Arm Helium vector processing technology for enhanced, energy-efficient digital signal processing (DSP) and machine learning (ML) performance. The Cortex-M55 offers an easy way to implement AI for IoT with the ease-of-use of Cortex-M, a single toolchain, optimized software libraries, and an industry-leading embedded ecosystem.

特色

Improve ML and DSP Performance

Delivers up to 15x ML performance improvement and up to 5x signal processing performance uplift compared to existing Cortex-M processors.

Accelerate Time to Market

The Corstone-300 reference design offers the fastest, most secure way to incorporate the Cortex-M55 into a system-on-chip (SoC).

Simplify Software Development

Single developer toolchain supported by a broad ecosystem of software, tools, libraries, and resources.

优势

Provide a security foundation, offering isolation to protect valuable IP and data with TrustZone technology.
Extend the processor operation with the tightly coupled co-processor interface.
Simplify the design and software development of digital signal control systems with the integrated digital signal processing (DSP) instructions.
Accelerate single precision floating-point math operations up to 10x over the equivalent integer software library with the optional floating point-unit.
Achieve industry-leading system energy efficiency using the integrated software controlled sleep modes, extensive clock gating, and optional state retention.
