* Add test for forwarding in ALU operations.Pavel Pisa2019-02-02
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Correct ALU test for SUB exception.Pavel Pisa2019-02-02
| | | | | | | | | | | | The operation 3 - 4 = 1 is legal integer arithmetic operation. Changed to 0x80000003 - 4 = 0x7fffffff 2147483651 - 4 = 2147483647 which overflows. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Include support for JALR support.Pavel Pisa2019-01-31
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Initial support for JAL.Pavel Pisa2019-01-31
| | | | | | | The JR, BEQ, BNE are most probably incorrect still. There is missing forwarding for pipelined execution. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Correct signed arithmetic overflow exception.Pavel Pisa2019-01-31

* 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 cache view rendererKarel Kočí2018-05-23
|
* Add cache statisticsKarel Kočí2018-05-23
|
* Fix load and store instructionsKarel Kočí2018-05-02
|
* Initial implementation of cache viewKarel Kočí2018-04-17
| | | | It needs some more work to look nice but it already works.
* Change presetsKarel Kočí2018-04-15
|
* Show cache statistics in Memory block in coreviewKarel Kočí2018-04-15
|
* Drop quick jump buttons from memory viewKarel Kočí2018-04-10
| | | | | They are not implemented and even if they would they usage would be little bit funky as they would jump by internal amount of page memory.
* Fix some instruction string representationKarel Kočí2018-04-08
|
* Change string format for some instructionKarel Kočí2018-04-08
| | | | This makes our string format closer to original assembler.
* Implement LUIKarel Kočí2018-04-08
|
* Implement sync for memoryKarel Kočí2018-04-08
|
* Ensure that set, block and assoc. is in minimum oneKarel Kočí2018-04-08
|
* Integrate cache with rest of the machine coreKarel Kočí2018-04-08
|
* Add associative cacheKarel Kočí2018-04-08
| | | | Not fully tested yet.
* Drop unneeded mask in memory implementationKarel Kočí2018-04-07
|
* Add initial implementatio of cachesKarel Kočí2018-04-07
|
* Just note that we are checking endianity automaticallyKarel Kočí2018-04-05
|
* Use whole words in memoryKarel Kočí2018-04-05
|
* 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.
* Implement Cache configurationKarel Kočí2018-03-06
| | | | This commit implements both cache configuration for machine and for gui.
* 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
|
* Another swap in instruction decodingKarel Kočí2018-02-14
|
* Swap rs and rt in I instructons decodingKarel Kočí2018-02-14

* Fix signextend in coreKarel Kočí2018-02-14
|
* Fix program loadingKarel Kočí2018-02-14
| | | | First section was ignored
* Various graphics tweaksKarel Kočí2018-01-27
|
* Add focus function to memory viewKarel Kočí2018-01-25
|
* Compile with debug symbols for DEBUG configKarel Kočí2018-01-25
|
* Add instruction view to single coreKarel Kočí2018-01-21
|
* Fix Pipelined core not to accept hazard unit configurationKarel Kočí2018-01-17
|
* Print I instruction immediate field in hexaKarel Kočí2018-01-17
|
* Update how configuration is handled in newdialogKarel Kočí2018-01-17
| | | | | | In previous implementation were dependencies described on two places. In NewDialog and in MachineConfig. Now NewDialog sets options in MachineConfig and configuration is then applied to NewDialog.
* Cleanup some todos in codeKarel Kočí2018-01-15
|
* Emit byte_change when byte is written to memoryKarel Kočí2018-01-15
|
* Fix program loader testKarel Kočí2018-01-15
|
* Fix SRA and SRAV instructionsKarel Kočí2018-01-15
| | | | | | This implementation is correct one but there is no guarantee that it will work with all compilers so we should always check on given platform that tests pass (and potentially fix it).
* Implement hazard unitKarel Kočí2018-01-15
