Overview

The Cortex-M0+ processor builds on the very successful Cortex-M0 processor, retaining full instruction set and tool compatibility, while further reducing energy consumption and increasing performance. Along with the Cortex-M0 processor, the exceptionally small silicon area, low power and minimal code footprint of these processors enable developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices. The Cortex-M0+ processor comes with a wide selection of options to provide flexible development.

Key features

  • Memory protection unit - Software reliability improves when each module is allowed access only to specific areas of memory required for it to operate. This protection prevents unexpected access that may overwrite critical data.
  • Binary upward compatible with all other Cortex-M processors - The Cortex-M0+ has mainly 16bit Thumb-2 instructions and few 32bit ones. These instructions are also present on all the other Cortex-M processors. Hence all code written for the Cortex-M0+ will run as is on the other processors.
  • Built-in low-power features - Sleep, deep sleep and state retention are three low power modes available to the user.
  • Optional Debug Access Port and Serial Wire Debug - For devices where every pin counts the serial wire debug port uses only two pins.
  • Optional Micro Trace Buffer - Trace all program flow via an in-memory trace buffer which can be read out via JTAG for later analysis.

Benefits

  • Extremely low power. The most energy efficient of all Arm processors. The Cortex-M0+ achieves a power consumption below 4µW/MHz (40LP process, base configuration), while reaching a performance of 2.46 CoreMark/MHz.
  • Versatile. The Cortex-M0+ includes optional functionalities that allow designers to reach an optimal fit-for-purpose solution for a broad range of applications. These include the single-cycle I/O interface for faster control, the Micro Trace Buffer (MTB) for enhanced debug, and others which are common to all Cortex-M processors, such as the Memory Protection Unit (MPU) and the relocatable vector table.
  • Fast time-to-market. The Cortex-M0+ processor is binary compatible to the Cortex-M0 and is upward binary compatible to all other Cortex-M processors making software re-use a real advantage. Developers also benefit from the Arm partnership’s extensive ecosystem of embedded tools, software, and knowledge base.

Announcing Arm AGI CPU: The silicon foundation for the agentic AI cloud era

For the first time in our more than 35-year history, Arm is delivering its own silicon products – extending the Arm Neoverse platform beyond IP and Arm Compute Subsystems (CSS) to give customers greater choice in how they deploy Arm compute – from building custom silicon to integrating platform-level solutions or deploying Arm-designed processors.

Encarsia: Evaluating CPU Fuzzers via Automatic Bug Injection

Hardware fuzzing has recently gained momentum with many discovered bugs in open-source RISC-V CPU designs. Comparing the effectiveness of different hardware fuzzers, however, remains a challenge: each fuzzer optimizes for a different metric and is demonstrated on different CPU designs.

Pie: Pooling CPU Memory for LLM Inference

Pie maintains low computation latency, high throughput, and high elasticity. Our experimental evaluation demonstrates that Pie achieves optimal swapping policy during cache warmup and effectively balances increased memory capacity with negligible impact on computation. With its extended capacity, Pie outperforms vLLM by up to 1.9X in throughput and 2X in latency. Additionally, Pie can reduce GPU memory usage by up to 1.67X while maintaining the same performance. Compared to FlexGen, an offline profiling-based swapping solution, Pie achieves magnitudes lower latency and 9.4X higher throughput.
