| * | Implement stall cycles counter and view of CPU cycles counter. | Pavel Pisa | 2019-04-02 |
| | | | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||
| * | Coreview multiplexers updated and added for branch compare forward. | Pavel Pisa | 2019-04-01 |

| * | Change single cycle core with delay slot to use separate fetch stage. | Pavel Pisa | 2019-03-26 |
| | | | | | | | | | | | | | When instructions are visualized then it is even more misleading to keep old instruction in decode phase delay buffer. The single cycle core with delay slot is upgraded to the variant with fetch and execute phases. This way the structure is logical and delay slot has purpose.

| * | Use irq 3 (HW1) for Rx and irq 2 (HW0) for Tx to be compatible with SPIM. | Pavel Pisa | 2019-03-04 |
| | | | | | | | | Jump to address 0x8000180 by default and to EBase + 0x180 when EBase is set to be compatible with real MIPS CPU. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||

| * | Add some more labels and clarify rs, rt, rd in execute stage. | Pavel Pisa | 2019-02-24 |
| | | | | | | | | This allows simple visual compare of rs and rt in execution stage with register number to be written in memory and write-back stages. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||

| | | | | | | | | | The new Qt5 syntax is used to create connections because old syntax does not work with multiple arguments for some unresolved reason. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||
| * | Add license to the source files. | Pavel Pisa | 2019-02-04 |

| * | Implement realistic hazard resolution for JR, JALR, BEQ, BNE, BLTZ, BGEZ ↵ | Pavel Pisa | 2019-02-02 |
| | | | | | | | | | | | | instructions. The previous code worked by chance only because decode has been fully processed including forwarding from M and W before PC processing started. But in real hardware the PC processing runs in parallel with ALU and cannot read its results in the same cycle. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||
| * | Initial support for JAL. | Pavel Pisa | 2019-01-31 |
| | | | | | | | | 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> | ||

| | | |||
| * | Implement little bit more of scheme and fix connection angle | Karel Kočí | 2018-01-21 |
| | | | | | | | | | | | This commit adds few more bits to scheme but mainly it chnages how connectors specify angles. Originally it was in radians but we was mapping that trough mathematical operations directly to sizes. But that was problematic because of floating point inacuracy and we sometimes founded intersection where there should be one. So this commit gets rid of this at all and instead allows just some fixes axes to be used instead of arbitrary angles. | ||

| * | Add instruction views to core view | Karel Kočí | 2018-01-15 |
| | | | | | Positioning and probably even graphics are just temporally for now. | ||
| * | Add connection between pc adder and multiplexer | Karel Kočí | 2018-01-09 |

| * | Clean and simplify how we add items to coreview | Karel Kočí | 2018-01-09 |

| * | Add coreview progress | Karel Kočí | 2018-01-08 |
| | | |||
| * | Add bounding box and make it grey | Karel Kočí | 2018-01-05 |
| | | | | | | This is just for development purposes. On release this bounding box should be dropped. | ||
| * | Fix how we handle scale of GraphicView | Karel Kočí | 2018-01-05 |
| | | | | | That widget is seriously buggy.. grr | ||
| * | Remove old scene in more appropriate place | Karel Kočí | 2018-01-05 |
| | | | | | | | Previous implementation was pretty confusing. There was no delete on level where variable override was happening. The object removal was implemented inside constructor. Very nasty. | ||
| * | Fix and suppress most of the warnings | Karel Kočí | 2018-01-05 |
| | | |||
| * | A lot of small changes in gui | Karel Kočí | 2017-12-21 |
