Previously CPLD programming involved a large 64kbyte buffer into which the the entire bitstream would be completely downloaded, and at which point the programming process would commence. This is needlessly wasteful of memory. Moreover, it could lead to USB timeouts as the firmware needs to wait the entire duration of the programming process before returning an ACK to the host after the final SETUP data phase packet. Instead, we now receive 512 byte chunks of the bitstream and stream them to the CPLD one at a time. We wait for each packet to be streamed out to the CPLD before ACKing the packet to prevent active data being overwritten.
