DTMF applications
The goertzel algorithm is area efficient approach for computing spectral energy on a single frequency for a digital input signal. The UTS provided goertzel IP core is useful for area optimized applications where energy on single frequency computation is required on a given FFT specification.

UTS offers IPs under flexible licensing models, to meet requirements of different category of users. The low cost reference designs are distinguished from IPs with less (or no) document (end user/project) execution for licensing.  Read more from IP main page.

UTS offers transparent and pre-committed pricing model for a minimum period of five years from the date of order  to migrate from per product based licensing to unlimited licensing or source code licensing models. With this the system developers have clear estimate of the cost in the volume production, right at the time of prototype development.

IP based on user specification

UTS also takes up development of complex algorithms based on the end performance specifications as per user requirements. In certain fields UTS also takes up this development on No cost - No commitment (NCNC) model. Based on the project category the UTS share on IP rights can be worked out for mutual benefit.
