* Display rs, rt, rd and write register number in all stages.Pavel Pisa2019-01-31
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Correct processing of ORI, ANDI, XORI instructions which require ↵Pavel Pisa2019-01-31
| | | | | | zero-extended immediate. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Do not replace rt by forward if instruction in T_R or store.Pavel Pisa2019-01-30
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Display execution stage forward signals in the view.Pavel Pisa2019-01-30
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Correct hazards processing.Pavel Pisa2019-01-30
| | | | | | | | The shorter loop has priority. This is achieved by later processing when it replaces possible result from longer loop over W stage. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Add few more labelsKarel Kočí2018-05-24
|
* Add buses statis viewsKarel Kočí2018-05-24
|
* Fix load and store instructionsKarel Kočí2018-05-02
|
* Implement LUIKarel Kočí2018-04-08
|
* Implement sync for memoryKarel Kočí2018-04-08
|
* Integrate cache with rest of the machine coreKarel Kočí2018-04-08
|
* Fix forwarding checker for I and J and S* instructionsKarel Kočí2018-03-06
| | | | THere are exceptions when we care about forwarding and when we don't.
* Forward from execute stage to decode stage latchKarel Kočí2018-02-14
|
* Do empty fetch stage to report fetch even if we stallKarel Kočí2018-02-14
|
* Fix signextend in coreKarel Kočí2018-02-14
|
* Add instruction view to single coreKarel Kočí2018-01-21
|
* Cleanup some todos in codeKarel Kočí2018-01-15
|
* Implement hazard unitKarel Kočí2018-01-15
|
* Allow instruction trace from any stageKarel Kočí2018-01-11
| | | | | | In reality this internally allows us to see stages even it we are not using pipelining but that is hidden from outside simply to not confuse user.
* Implement machine restartKarel Kočí2018-01-05
|
* Allow delay slot disable for non-pipelined coreKarel Kočí2018-01-03
|
* Add trace-feth to qtmips_cliKarel Kočí2018-01-03
|
* Put qtmips_machine to machine namespaceKarel Kočí2017-12-17
|
* Implement some store and load instructionsKarel Kočí2017-12-12
|
* Fix immediate alu operationKarel Kočí2017-12-12
| | | | | There should be a sign extension to 32bit when doing immediate operations.
* Implement branch and jump instructionsKarel Kočí2017-12-12
|
* Add crude implementation of MOV* instructionsKarel Kočí2017-11-25
| | | | I don't like how it's implemented but I have no other idea atm.
* Implement instructions for moving from and to HI and LO registersKarel Kočí2017-11-25
|
* Test pipelined coreKarel Kočí2017-11-25
|
* Implement some logical operationsKarel Kočí2017-11-21
|
* Implement some immediate arithmetic instructionsKarel Kočí2017-11-21
|
* Implement and test ADDKarel Kočí2017-11-21
|
* Another huge pile of work for about two monthsKarel Kočí2017-11-19
| | | | | | Well I should commit every change instead of this madness. I am not documenting changes as all this is just improvements and implementation progression.
* Initial commitKarel Kočí2017-08-30
Adding work done so far.
