Abstract

USB 3.0 sabirnica omogućuje brzine prijenosa digitalnog video signala do 5 Gb/s. U FPGA sklopu sirovi video signal formatiran je u tok podataka po USB Video Class (UVC) standardu. Logički sklop za tok ulaznog neformatiranog i izlaznog UVC formatiranog video signala podržava ARM AMBA AXI4-Stream sučelje. CYUSB3014 (EZ-USB-FX3) mikrokontroler omogućuje prijenos podataka preko USB 3.0 sabirnice. Za prijenos podataka putem FX3-a potrebna je priključnica (engl. Socket), DMA opisnik, DMA spremnik i GPIF niti. DMA opisnik sadrži informaciju o adresama i veličini DMA spremnika. U jedan DMA spremnik upisuju se parni paketi, a u drugi neparni. Paketi su veličine 16 kB, a zadnji paket okvira može biti kraći. Za upravljanje prijenosa podataka prema DMA spremniku projektiran je sklop GPIF Slave FIFO.

Abstract (english)

USB 3.0 standard allows high speed digital video signal transfer with speeds up to 5 Gb/s. FPGA is used to encode video signal into a data stream which is compliant with USB Video Class (UVC) standard. Logic controller which receives unformatted data stream and transmits UVC compliant data stream supports ARM AMBA AXI4-Stream interface. CYUSB3014 (EZ-USB-FX3) microcontroller allows data transfer via USB 3.0 bus. FX3 utilizes Socket, DMA descriptor, DMA buffer and GPIF thread to support data transfer. DMA descriptor holds information about address and size of DMA buffers. Packets with odd index numbers are written into first DMA buffer, and packet with even index number are written into second DMA buffer. Each packet has size of 16kB, while last packet in the stream can be shorter. GPIF Slave FIFO is used to manage data transfer into DMA buffer.
