    • AXI4 busmaster interface to FX3 GPIF2 slave FIFO interface

      We will introduce a new IP core for EFM-02 next week: a AXI4 busmaster bridge to FX3's GPIF2 slave FIFO interface (EZ-USB® FX3™ USB Controller - Cypress Semiconductor). It is already working nicely and stable but needs some throughput optimizations. Using this IP, the PC can access an AXI bus inside the FPGA using the "memcpy"-like read/write commands of the UDK3. In parallel to other AXI4 bus masters like Microblaze or something. This makes the usage of USB 3.0 in projects so amazing easy... Incredible !
