Biyomedikal uygulamaları son yılların önemli araştırma alanlarından biridir. Bu çalışma alanlarından birisi de biyomedikal sinyallerdir. Bu çalışmada, VHDL ile Xilinx-Vivado programı kullanılarak, yaşamsal belirti sinyallerine ait iki aritmik (II. Derece AV-blok tip-1 ve II. Derece AV-blok tip-2) EKG sinyali FPGA çipleri üzerinde çalışmak üzere tasarlanmış ve uygulanmıştır. Nümerik tabanlı EKG sinyalleri referans olarak alınmış ve FPGA tabanlı EKG sinyal tasarımından elde edilen sonuçlarla karşılaştırılmıştır. Daha sonra tasarımda kullanılan yapı ve çalışmadan elde edilen test sonuçları sunulmuştur. Tasarlanan EKG sinyalleri Zynq-7000 TC7Z020 FPGA için sentezlenmiştir ve 14 kanallı AN9767 DA modülü kullanılarak osiloskoptan gözlemlenmiştir. Place-Route işlemi sonrasında elde edilen FPGA çip kaynak tüketim değerleri sunulmuştur. Sonuçlara göre II. Derece AV-blok tip-1 sinyallerinin FPGA üzerinde en yüksek çalışma frekansı 651.827 MHz ve II. Derece AV-blok tip-2 sinyallerinin FPGA üzerinde en yüksek çalışma frekansı 663.504 MHz belirlenmiştir. FPGA tabanlı EKG sinyal tasarımından elde edilen maksimum MSE hata değerleri II. Derece AV AV-blok tip-1 sinyali için 2.0011E-03 ve II. Derece AV-blok tip-2 sinyali için 1.2754E-04’tür. Bu çalışmada, donanımsal olarak gerçeklenen FPGA tabanlı 2. derece AV blok aritmik EKG sinyalleri üretim sisteminin biyomedikal kalibrasyon uygulamalarında güvenle kullanılabileceği gösterilmiştir.

Design of FPGA-based 2nd Degree AV Block Arrhythmic ECG Signals with VHDL

Öz

Studies in the field of biomedicine are one of the substantial study areas that have recently taken place in the literature. Studies in these research areas are based on the processing of vital sign signals. This paper presents the design and implementation of two arrhythmic (2nd degree AV-block type-1 and 2nd degree AV-block type-2) ECG signs to be used in FPGA with Xilinx-Vivado software utilizing VHDL. Numeric ECG signs were taken as reference, then confront with values related to the design of FPGA based ECG sign. Design utilized in the implementation and test outcomes got from the work have been introduced. Implemented ECG signs have been synthesized for Zynq-7000 TC7Z020 FPGA and tracked using oscilloscope using 14-channel AN9767 DA module. After Place&Route, FPGA chip statistics were introduced. The maximum working frequencies of 2nd degree AV Block Type-1 signs and 2nd degree AV Block Type-2 signs in FPGA have been obtained as 651.827 MHz and 663.504 MHz, respectively. Maximum MSE rates from the FPGA-based ECG sign implementation for 2nd degree AV Block Type-1 and 2nd degree AV Block Type-2 signs have been obtained as 2.0011E-03 and 1.2754E-04, respectively. This paper demonstrates that the hardware designed FPGA-based ECG sign production system can be implemented on FPGA and can be utilized snugly in biomedical calibration applications. This paper demonstrates that FPGA-based ECG signal generation system, which is implemented as hardware, can be designed using FPGA chips and can be safely used in biomedicine areas.
