- ibdr_dl11
- now xbuf.val in bit 15 and 8;
- use rbuf instead xbuf for rdry reporting
- remove maintenance mode
- use ib_rlim_slv; add RLIM_CEV, drop CE_USEC
- ibdr_pc11
- pbuf.pval in bit 15 and 8
- move rbusy reporting from pbuf to rbuf register
- ibdr_maxisys,ibdr_minisys: adapt to new ibdr_dl11 iface
- tb_rlink_tba_pdp11core_ibdr.dat: adapt to new ibdr_dl11 iface
- tcl/rw11/util.tcl: setup_tt: rename dlrlim to dlrrlim
- oskit/*/*_boot.tcl: use dlrrlim instead of dlrlim
- Rw11CntlDL11,Rw11CntlPC11: adapt to new dl11,pc11 iface
- tools/asm-11/lib/defs_{dl,pc}.mac: added definition file
- tools/oskit/hook/hook_ibmon_{pca,tta}.tcl: added imon hook file
- pdp11_sys70: drop ITIMER,DM_STAT_DP, use DM_STAT_EXP, add PERFEXT port
- pdp11_sequencer: drop ITIMER port, use DM_STAT_SE.itimer
- sys_w11a_*.vhd: use DM_STAT_EXP
- some re-wiring, no functional change to CPU or IO system
- pdp11_sequencer.vhd: CPUERR cleared by CRESET
- mminki.mac: added, procedure to initialize MMU, kernel I space only
- test_w11a_cpuerr.tcl: added, test cpuerr register
- added more README's
- editorial changes
- xsim support complete (but many issues to be resolved yet)
- Added configurable w11a cache
- Removed some never documented and now strategically obsolete designs
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
divisor or quotient were the largest negative integer (100000 or -32768).
This is corrected now, for details see ECO-026-div.txt
- some minor updates and fixes to support scripts
- xtwi usage and XTWI_PATH setup explained in INSTALL.txt
- C++ and Tcl based backend server: many support classes for interfacing to
w11 system designs, and the associated Tcl bindings.
- add 'asm-11', a simple, Macro-11 syntax subset combatible, assembler.
- use now doxygen 1.8.3.1, generate c++,tcl, and vhdl source docs
- 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 !!
- added xon/xoff (software flow control) support to serport library
- added test systems for serport verification
- use new serport stack in sys_w11a_* and sys_tst_rlink_* systems
- re-organize modules 'human I/O' interface on Digilent boards
- add test designs for 'human I/O' interface for atlys,nexys2, and s3board
- small updates in crc8 and dcm areas
- with one exception all vhdl sources use now numeric_std
