rbus->ibus window. Replaces with a 4k word window for whole IO page.
- utilize rlink protocol version 4 features in w11a backend
- use attn notifies to dispatch attn handlers
- use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
- use labo and merge csr updates with last block transfer
- this combined reduces the number of round trips by a factor 2 to 3,
and in some cases the throughput accordingly.
- Goals for rlink v4
- 16 bit addresses (instead of 8 bit)
- more robust encoding, support for error recovery at transport level
- add features to reduce round trips
- improved attention handling
- new 'list abort' command
- For further details see README_Rlink_V4.txt
- use own C++ based tcl shell tclshcpp instead of tclsh
- C++ and Tcl based backend server now fully functional, supports with
DL11, RK11, LP11 and PC11 all devices available in w11a designs
- the old perl based backend server (pi_rri) is obsolete and removed
- operating system kits reorganized
- Added simple simulation model of Cypress FX2 and test benches for
functional verifcation of FX2 controller
- Bugfixes in FX2 firmware and controller, works now also on Nexys3 & Atlys
- Added test systems for rlink over USB verification for Nexys3 & Atlys
- re-organized handling of board and derived clocks in test benches
- added message filter definitions for some designs (.mfset files)
- added Cypress EZ-USB FX2 controller (USB interface)
- added firmware for EZ-USB FX2 supporting jtag access and data transfer
- FPGA configure over USB now supported directly in make build flow
- added test systems for USB testing and rlink over USB verification
- no functional change of w11a CPU core or any pre-existing test systems
- Note: Carefully read the disclaimer about usage of USB VID/PID numbers
in the file README_USB-VID-PID.txt. You'll be responsible for any
misuse of the defaults provided with the project sources !!
