* 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
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* 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>
* Specify rpath during linking to find qtmips_machine library without install.Pavel Pisa2019-01-30

* Hide some values that shouldn't been visible in no pipelined versionKarel Kočí2018-06-20
|
* Fix value position for non-pipelined coreKarel Kočí2018-05-24
|
* Add few more labelsKarel Kočí2018-05-24
|
* Add few additional labelsKarel Kočí2018-05-24
|
* Add buses statis viewsKarel Kočí2018-05-24
|
* Add cache view rendererKarel Kočí2018-05-23
|
* Ignore hazard unit for nowKarel 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.
* Drop unneeded parameter from CoreViewScene constructorKarel Kočí2018-04-17
|
* Fix angle scroll speedKarel Kočí2018-04-17
| | | | | I finally manage to make device to report as angle scroll device. And it was too fast scroll so I make it solver. It is now some what acceptable.
* Store memory and program view address positionKarel Kočí2018-04-17
| | | | | | This reloads memoryview with same base address as it was closed with. It somewhat works but with program view it seems to be buggy and shifts stuff down. But let's say that it's good enough for now.
* When changing focus load it back to edit field in memoryviewKarel Kočí2018-04-15
|
* Add 2x speedKarel Kočí2018-04-15
|
* Disable memory protection configuration fields for nowKarel Kočí2018-04-15
| | | | | Memory protection is not feature that is strictly required. Because of that it's implementation has lower priority.
* Change presetsKarel Kočí2018-04-15
|
* Rename CoreView to GraphicsViewKarel Kočí2018-04-15
| | | | | This generalizes CoreView to be used with other parts of the project too.
* Add cache dockKarel Kočí2018-04-15
|
* Fix coverview memory cacheKarel Kočí2018-04-15
| | | | Text was always rendered.
* Show cache statistics in Memory block in coreviewKarel Kočí2018-04-15
|
* Disable program followKarel Kočí2018-04-14
| | | | | | | | This should be easy enought to program but it requires some deeper changes to memoryview it self (to allows direct address to item mapping). Because of that I am disabling it for now and I will return to this feature in future. For now I am focusing on other more important aspects of qtmips (to make it feature complete not nice to use).
* Wire up missing control connectionsKarel Kočí2018-04-14
| | | | | Now only hazard unit is missing all wires. Anything else is wired up already.
* 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
|
* Don't insert another column when statictable widget is not widerKarel Kočí2018-04-08
| | | | | This makes static table widget to have only one column until it's wider then higher.
* 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.
* Tweak shortcuts for primary windowKarel Kočí2018-04-07
|
* 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
|
* Add control signals for non-pipelined cpuKarel Kočí2018-03-22
|
* Append some TODOsKarel Kočí2018-03-06
