- Summary
|
240 |
11 |
wfjm |
- Introduce C++ and Tcl based backend server. A set of C++ classes provide
|
241 |
16 |
wfjm |
the basic rlink communication primitives. Additional glue classes provide
|
242 |
11 |
wfjm |
a Tcl binding. This first phase contains the basic functionality needed
|
243 |
|
|
to control simple test benches.
|
244 |
|
|
- add an 'rlink exerciser' (tst_rlink) and a top level design for a Nexys2
|
245 |
|
|
board (sys_tst_rlink_n2) and a test suite implemented in Tcl.
|
246 |
|
|
|
247 |
|
|
- Note: No functional changes in w11a core and I/O system at this point!
|
248 |
|
|
The w11a demonstrator systems are still operated with the old
|
249 |
|
|
backend code (pi_rri).

wfjm |
- the rri (remote-register-interface) components were re-organized and
|
298 |
|
|
cleanly separated into rbus and rlink components:
|
299 |
|
|
rri/rb_sres_or_* -> rbus/rb_sres_or_*
|
300 |
|
|
rri/rri_core -> rlink/rlink_core
|
301 |

rri/rri_base_serport -> rlink/rlink_base_serport
|
302 |
|
|
rri/rrilib -> rbus/rblib
|
303 |
|
|
-> rlink/rlinklib
|
304 |
|
|
rri/rri_serport -> rlink/rlink_serport
|
305 |
|
|
rri/tb/rritb_sres_or_mon -> rbus/rb_sres_or_mon
|
306 |
|
|
- the rri test bench monitors were reorganized and renamed
|
307 |
|
|
rri/tb/rritb_cpmon -> rlink/rlink_mon
|
308 |
|
|
rri/tb/rritb_cpmon_sb -> rlink/rlink_mon_sb
|
309 |
|
|
rri/tb/rritb_rbmon -> rbus/rb_mon
|
310 |
|
|
rri/tb/rritb_rbmon_sb -> rbus/rb_mon_sb
|
311 |
|
|
- the rri low level test bench were also renamed
|
312 |
|
|
rri/tb/tb_rri -> rlink/tb/tb_rlink
|
313 |
|
|
rri/tb/tb_rri_core -> rlink/tb/tb_rlink_direct
|
314 |
|
|
rri/tb/tb_rri_serport -> rlink/tb/tb_rlink_serport
|
315 |
|
|
- the base modules for rlink+cext based test benches were renamed
|

rri/tb/rritb_core_cm -> rlink/tb/tbcore_rlink_dcm
|
317 |
|

|
rri/tb/cext_rriext.c -> rlink/tb/rlink_cext.c
|
320 |
|
|

321 |
|
|
- other rri/rbus related renames
|
322 |
|
|
bplib/s3board/s3_humanio_rri -> s3_humanio_rbus
|
323 |
|
|
w11a/pdp11_core_rri -> pdp11_core_rbus

|
|
w11a/tb/tb_pdp11_core -> tb_pdp11core
|
327 |
|
|
|
328 |
|
|
- signal renames:
|
329 |
|
|
- rlink interface (defined in rlink/rlinklib.vhd):
|
330 |
|
|
- rename rlink port signals:
|
331 |
|
|
CP_* -> RL_*
|
332 |
|
|
- rename status bit names to better reflect their usage in v3:
|
333 |
|
|
ccrc -> cerr - indicates cmd crc error or other cmd level abort
|
334 |
|
|
dcrc -> derr - indicates data crc error or other data level abort
|
335 |
|
|
ioto -> rbnak - indicates rbus abort, either no ack or timeout
|
336 |
|
|
ioerr -> rberr - indicates that rbus err flag was set
|
337 |
|
|
|
338 |
16 |
wfjm |
- migrate to rbus protocol version 3
|
339 |
9 |
wfjm |
- in rb_mreq use now aval,re,we instead of req,we
|
340 |
|
|
- basic rbus transaction now takes 2 cycles, one for address select, one
|
341 |
|
|
for data exchange. Same concept and reasoning behind as in ibus V2.
|
342 |
|
|
|
343 |
|
|
- vlib/rlink/rlink_core
|
344 |
|
|
- cerr and derr state flags now set on command or data crc errors as well
|
345 |
|
|
as on eop/nak aborts when command or wblk data is received.
|
346 |
|
|
- has now 'monitor port', RL_MONI.
|
347 |
|
|
- RL_FLUSH port removed, the flush logic is now in rlink_serport
|
348 |
|
|
|
349 |
|
|
- restructured rlink modules
|
350 |
|
|
- rlink_core is the rlink protocol engine with a 9 bit wide interface
|
351 |
|
|
- rlink_rlb2rl (new) is an adapter to a byte wide interface
|
352 |
|
|
- rlink_base (new) combines rlink_core and rlink_rlb2rl
|
353 |
|
|
- rlink_serport (re-written) is an adapter to a serial interface
|
354 |
|
|
- rlink_base_serport (renamed) combines rlink_base and rlink_serport

- in future 'box' is used for large autonomous blocks, therefore use
|
375 |
|
|
the term unit for purely sequential logic modules:
|
376 |
|
|
pdp11_abox -> pdp11_ounit
|

pdp11_dbox -> pdp11_aunit
