- ibdr_maxisys: add IDEC port, connect to EXTEVT of KW11P
- sys_w11a_*.vhd: use DM_STAT_EXP; IDEC to maxisys; setup PERFEXT
- kw11p and dmpcnt now fully setup
- 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
- s3_sram_memctl: drop superfluous idata_cei=1 in s_write2
- arty_bram/tb/tbrun.yml: retire mem70 - now in tbcpu
- tst_sram.vhd: allow AWIDTH=17; sstat_rbf_awidth instead of _wide
- tcl/tst_sram/*.tcl: 17bit support; use sstat(awidth); add isnarrow
- rtl/vlib/rutil.vhd: added package, with imin helper function
- xviv_msg_filter: add version-range tag support
- *.vmfset:
- drop the nonsense 'Synth 8-6014' messages
- adopt to different path used by 'Synth 8-3332' messages
- dmcmon has now the sta,sto,sus,res logic as rbmon and ibmon
- dmcmon does not depend on full state number generation anymore
- dmcmon missed WAIT instructions so far, has been fixed
- related changes:
- pdp11_sequencer can now return a simple instruction type based snum
- sys_w11a_n4 includes dmcmon again (now independent of dmscnt!)
- 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
- new reference system
- switched from ISE 13.3 to 14.7.
- map/par behaviour changed, unfortunately unfavorably for w11a.
On Nexys3 no timing closure anymore for 80 MHz, only 72 MHz can
be achieved now.
- new man pages (in doc/man/man1/)
- support for Spartan-6 CMTs in PLL and DCM mode
- 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
- new C++ and Tcl based backend server supports now RK11 handling
- w11a systems operate with rlink over USB on nexsy2 and nexsy3 boards.
See w11a_os_guide.txt for details
