As we see spectacular growth in the number of autonomous, intelligent, and connected devices (particularly for the Internet of Things, or IoT), which are required to operate in a low-power environment. In response, manufacturers are increasingly turning to place the Arm Cortex processors at the heart of these devices. In addition to industry-leading IP, Arm offers the world’s #1 ecosystem, in which partners provide software libraries and a large set of software and development tools.
Advantages of powerful DSP extensions in Cortex processorsSome 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++, rather than the handcrafted assembler often used for a proprietary DSP.
Whatever your requirements for signal processing, Arm offers the right solution for the right application.
|Your need||Arm solution|
|Highest performance:||Cortex-A + NEON|
|Hard real-time:||Cortex-R + DSP, Cortex-R52 + NEON|
|Energy efficiency:||Cortex-M + DSP|
