DSP extensions

Trusted Arm processors with signal processing


Arm Cortex processors are found at the heart of autonomous, intelligent, and connected devices. From Internet of Things (or IoT) to industrial control, from medical to consumer; manufacturers are using the DSP capabilities of Cortex processors to perform the signal processing required in these devices. Developers are taking advantage of industry-leading IP and the world's #1 ecosystem, with an extensive set of Arm and partner provided software libraries and the broadest set of software and development tools.

Advantages of powerful DSP extensions in Cortex processors

Some of the key benefits of DSP extensions in Cortex processors are:
  • Significant savings on the BOM (bill of materials, i.e. cost of products), by replacing two processors with one.
  • Reduced system-level complexity by removing the need for shared memory and DSP communication, complex multiprocessor bus architectures, and other custom ‘glue’ logic between the processor and DSP.
  • Reduced software development costs, because the entire project can be supported using a single compiler/debugger/IDE, and is programmable in a high-level programming language such as C or C++.

Whatever your requirements for signal processing, Arm offers the right solution for the right application.
