| Abstract |
| | This paper covers the aspects of the recurrency principle in the digital signal processing domain. The existing implementation of the tag transformer in an operating unit was found lacking in practice. Therefore, we research the applicability of specialized recurrent tag transformers in a recurrent operating unit for the tasks of digital signal processing.
We analyzed the existing recurrency implementation in an operating device based on the data-flow principles. The discovered deficiencies are described. The hypothesis for specialized recurrent chains efficiency is proposed. An analysis is made of a limited subset of digital signal processing algorithms with the aim of constructing specialized recurrent chains and their respective tag transformers.
The construction results of several specialized tag transformers are presented. The Butterworth demo filtering algorithm implementation using those transformers is presented as well.
The performance of the operating unit on the basis of a library of specialized transformers is confirmed. The programmability simplification is proposed via the introduction of the specialized transformers library. Potential architectural improvements through redundancy required for previous implementation removal is proposed. |
