Near Field Communication (NFC) is an ubiquitous technology with many applications ranging from identification to ticketing, from mobile payment to logistical solutions and, just recently, wireless charging. Every modem unit must be able to support multiple communication standards in different operative conditions. In many cases, this is achieved by means of an extensive use of custom DSP logic at the expense of full functional flexibility and of an high engineering effort, which could be unacceptable from the business perspective. One way to balance chip-resources with the growing need for flexibility is to consider the adoption of RTL microprocessors able to perform DSP instructions.
