Akustik Atiş Yeri Tespit Sistemi için FPGA Tabanli Eşlenik Süzgeç Gerçekleştirilmesi

In this paper, a matched filter commonly used in acoustic shot detection algorithms was implemented on an FPGA (Field Programmable Gate Array) of a system on chip using a hardware-software co-design method. The matched filter design processes data from four microphone channels in parallel through cross-correlation and is capable of detecting shock wave signals and generating interrupts to transfer information to the processor upon detection. Custom design IP (Intellectual Property) blocks were designed and utilized in the study. The synchronization of the used IP blocks and the design details were explained. The design was implemented in an system on chip and its results were observed. As a result, a hardware implementation example of signal processing applications such as matched filters, which are time-consuming and consume processor resources when frequently called and used for many channels, was demonstrated.
