* Memory change counter moved to MemoryAccess and external changes ↵Pavel Pisa2019-06-30
| | | | | | | | | | | notification added. This change together with use of PhysAddrSpace as the memory content source for memory and program view allows to access and monitor contents of peripheral registers and frame-buffer memory from graphic user interface. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Initial optimized version LCD display emulation.Pavel Pisa2019-06-28
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Allow to create simulator without loaded executable.Pavel Pisa2019-06-26
| | | | | | | This allows to test simple instruction sequences without need to install compiler. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Extend qtmips_cli to recognize break and report final state.Pavel Pisa2019-03-24
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Enable configuration of syscalls emulation and stop on exception.Pavel Pisa2019-03-06

* Dock to view coprocessor 0 and cop0 counter/comparator support.Pavel Pisa2019-03-05
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Implemented interrupt delivery and processing for serial port.Pavel Pisa2019-03-04

* Implemented coprocessor 0 registers access and register EPC and Cause set by ↵Pavel Pisa2019-03-04

* Add support for goto to selected symbol address.Pavel Pisa2019-02-22

* Implemented three dials equivalent to MZ_APO RGB dials.Pavel Pisa2019-02-13
| | | | | | | Tested with code compiled by Linux PIC based GCC compiler with calling musl-libc sprintf function. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Include simple serial port terminal and prepare empty peripheral dock.Pavel Pisa2019-02-13
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Add speed option to run core for time chunks without visualization.Pavel Pisa2019-02-13
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Make memory and program listing editable.Pavel Pisa2019-02-12
| | | | | | Instruction parsing is rough and does not support branch offset computation. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Display red background for instruction causing exception and skip HW ↵Pavel Pisa2019-02-11
| | | | | | | | | | breakpoint for first cycle after resume. Instruction for stage is updated when given stage is flushed as well. But other signals are left intact, it is duty of memory stage to discard effect of instruction causing interrupt. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Basic "hardware" breakpoints support implemented.Pavel Pisa2019-02-11
| | | | | | | | | | It works like real inserted breakpoint on hardware. Breakpoint has to be removed to allow code continue because else instruction is refetch and breakpoint triggers again. The single step function should resolve temporal masking of the breakpoint. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Prepare core for "hardware" breakpoints support and add signals to follow ↵Pavel Pisa2019-02-11
| | | | | | stages. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Make function to register exception handler accessible from outside.Pavel Pisa2019-02-08
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Provide at least partial cleanup after QtMipsMachine.Pavel Pisa2019-02-06
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Implement simple address-space ranges registration and example peripheral.Pavel Pisa2019-02-06

* Add license to the source files.Pavel Pisa2019-02-04

* Correct memory view updates for uncached and write-through case.Pavel Pisa2019-02-03

* Integrate cache with rest of the machine coreKarel Kočí2018-04-08
|
* Cleanup some todos in codeKarel Kočí2018-01-15
|
* Add ability to get specific core type from qtmipsmachineKarel Kočí2018-01-08
|
* Copy machineconfig in QtMipsMachineKarel Kočí2018-01-05
|
* A lot of small changes in guiKarel Kočí2017-12-21
| | | | | | Added machine status. Widgets now hold size and registers dock has now scrollbars. And more...
* Use global includes in qtmips_machineKarel Kočí2017-12-17
|
* Put qtmips_machine to machine namespaceKarel Kočí2017-12-17
|
* Implement few initial graphic elementsKarel Kočí2017-12-15
|
* 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.
