Such performance improvements have led to the introduction of digital signal processing in commercial [[communications satellite]]s where hundreds or even thousands of analog filters, switches, frequency converters and so on are required to receive and process the [[uplink]]ed signals and ready them for [[downlink]]ing, and can be replaced with specialised DSPs with significant benefits to the satellites' weight, power consumption, complexity/cost of construction, reliability and flexibility of operation. For example, the SES-12 and SES-14 satellites from operator [[SES S.A.|SES]] launched in 2018, were both built by [[Airbus Defence and Space]] with 25% of capacity using DSP.<ref>''[[Beyond Frontiers]]'' Broadgate Publications (September 2016) pp22</ref>

The architecture of a DSP is optimized specifically for digital signal processing. Most also support some of the features asof an applications processor or microcontroller, since signal processing is rarely the only task of a system. Some useful features for optimizing DSP algorithms are outlined below.
