Enhanced Arm DesignStart: the fastest and lowest-risk path to custom SoCs

For the best part of a decade, Arm DesignStart has helped thousands of chip developers – the technology innovators of today – get quick, easy and free access to Arm IP. Arm is accelerating innovation in smart embedded devices even further with significant enhancements to DesignStart that provide the fastest, simplest access to proven, trusted IP, and the most comprehensive route to silicon success.

The latest enhancements to Arm DesignStart, making custom SoCs even more accessible, include:

  • The addition of the Arm Cortex-M3 processor – the mainstream processor for connected intelligence. This joins Cortex-M0, and together, they enable designers to address the broadest spectrum of smart embedded and custom SoCs
  • Elimination of upfront license fees for both the Cortex-M0 and Cortex-M3 processors.  Companies can now develop their chip with a success-based, royalty-only model
  • Instant, no-cost access to both processors for design, simulation and prototyping
  • Accelerated time to market for Cortex-M3 based designs with the CoreLink SDK100, with its verified subsystem and system IP
  • Additional SoC design services, so that even companies without chip development experience can benefit from having a customized SoC

Access to trusted IP has never been easier

DesignStart Eval and DesignStart Pro

There are two ways to access industry-leading processor IP through DesignStart:

  • DesignStart Eval enables anybody to click and get instant access to Cortex-M0, Cortex-M3 and their subsystems. Designers can configure or modify the subsystem, add their own IP and peripherals, and then prototype on an FPGA.
  • DesignStart Pro is for companies looking to develop their own chip.  Companies simply register on the DesignStart website, sign and return a simplified contract, then start building their chip.  No upfront fees, just a simple success-based royalty once they are in production.

Accessing proven, trusted IP has never been easier with Arm DesignStart

What is included in DesignStart Pro?

Start developing your production chip with DesignStart Pro, with a $0 upfront license fee. Access is easy: companies simply register, sign and return a simplified agreement and then download the IP. Benefits include:

  • Fast, simplified, no-risk access to Cortex-M0, Cortex-M3 and subsystems for commercial chip development (no upfront fee, just a small, success-based royalty)
  • Develop a complete IoT or smart embedded solution using Cortex-M3 with a verified subsystem design, enhanced design services and mbed OS platform

DesignStart Pro is available for both Cortex-M0 and Cortex-M3

  • Cortex-M0 with Cortex M0 System Design Kit
  • Cortex-M3 with CoreLink SDK-100, including a fully verified subsystem and system IP 

Out-of-the-box Cortex-M3 system design with CoreLink SDK-100

To help speed the creation of SoCs, DesignStart Pro for Cortex-M3 includes a fully verified  subsystem around which developers can add their peripherals, memory, sensors and other analog IP.  The Arm CoreLink SSE-050 subsystem offers a combination of hardware and software to enable designers to concentrate on the differentiating features and end application of their SoC. 

Simplify the creation and deployment of IoT solutions with mbed OS

Cortex-M3 DesignStart supports mbed OS: software designed specifically for IoT devices that brings a comprehensive suite of security elements and connectivity that makes the creation and deployment of IoT solutions possible at scale.  It includes all the features needed to develop a connected product , including security, connectivity, an RTOS and drivers for sensors and I/O devices.

Proven, industry-leading IP – and much more

With the addition of Cortex-M3, DesignStart enables companies to create the broadest range of smart embedded devices. Not only does it offer fast, simple and no-risk access to IP, it also provides the most proven IP. 

  • Arm has shipped over 20 billion Cortex-M0 and Cortex-M3 based chips 
  • The Cortex-M0 and Cortex-M3 CPUs are the highest-shipping Cortex-M cores
  • ½ million Cortex-M0 and Cortex-M3 based SoCs ship every hour!

If you are developing a chip, you want the confidence of knowing the IP has been used in hundreds of different chips, in hundreds of different configurations. With Arm Cortex-M0 and Cortex-M3 CPUs, you can trust you are getting reliable, proven technology for your product.

Arm DesignStart enables the broadest range of embedded devices

The Cortex-M0 processor

The Arm Cortex-M0 processor is the smallest Arm processor available. The exceptionally small silicon area, low power and minimal code footprint of the processor enables developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices.
