FTDI are set to release a series of USB3.0 devices to complement their renowned USB endpoint-to-FIFO bridge USB 2.0 (FT232H) and USB 1.1 (FT245) ones, which have been available for a few years. Available with optional 16-bit and 32-bit FIFO interfaces, the FT600 will be the first device released in the series. This is splendid news and music to the ears of the FPGA community, as the device could be used to provide FPGA enhanced applications with simplified connectivity to host computers, with data transfer rates of up to 5 Gpbs.
This is a blog about our everyday exploits in all aspects of everything. From science, art, computing, engineering, playing badminton to even playing computer games. Just about everything!
The aim of the set of posts in this section of this blog category is to develop an USB protocol debugger and analyser that can extract USB 2.0 data, from a USB data stream, in real time and fed the stream to a PC, which will typically host a Linux operating system. Although some processing of the USB data stream may take place in the FPGA in the first instance the stream will be buffered in external memory attached to the FPGA and sent in its raw form to the PC.
