Soft-Core architecture for Analogue to Digital Converter (ADC) sampling 9 is useful for mixed signal applications. Soft-core architecture for cutting edge odd or 10 even ADC sampling with interface to block RAM memory has not been found. 11Soft-core architecture as a concept has become popular due to the advantage of 12 customization for different applications as compared to general-core architecture 13 suited for single application. The latest generation of piecewise sampling is odd 14 sampling and was introduced in the second decade of the 20th century. Odd and 15 even order sampling techniques are analogue in nature driven by a tuned (tuned for 16 odd or even) mixer. This paper proposes a third-generation piecewise sampling with 17 soft-core architecture that enables an option to select both odd and even while 18 interfacing to memory mapping. The proposed odd/even has superior SNR 19 performance of 6 dB as compared to existing architecture such as Mod-∆ which 20 recorded worst performance of 18 dB. Advances in soft-core technology have allowed a 21 niche odd/even switching field to be identified and studied, the study has also been 22 extended to include memory architecture. 23

Digitization is at the center of fourth industrial revolution (4IR) with previously analog systems being digitized through an analog-to-digital converter. In addition, 4IR applications such as fifth generation (5G) Cellular Networks Technology and Cognitive Electronic Warfare (EW) at some point interface digitally through an analog-to-digital converter. Efficient use of digital resources such as memory, largely depends on the signal sampling design of analog-to-digital converters. Existing even order sampling has been found to perform better than traditional sampling techniques. Research on the efficiency of a digital interface with a 4IR platform is still in its infancy. This paper presents a performance study of three sampling techniques: the proposed new and novel odd/even order sampling architecture, existing Mod-∆, and traditional 1st order delta-sigma, to address this. Step-size signal-to-noise (SNR), dynamic range, and sampling frequency are also studied. It was found that the proposed new and novel odd/even order sampling achieved an SNR performance of 6 dB in comparison to 18 dB for Mod-∆. Sampling frequency findings indicated that the proposed new and novel odd/even order sampling achieved a sampling frequency of 2 kHz in comparison to 8 kHz from a traditional 1st order sigma-delta. Dynamic range findings indicated that the proposed odd/even order sampling has achieved a dynamic range of 1.088 volts/ms in comparison to 1.185 volts/ms from a traditional 1st order sigma-delta. Findings have indicated that the proposed odd/even order sampling has superior SNR and sampling frequency performances, while the dynamic range is reduced by 8%.
