a70e12ad75 Optimization in the ifu. Please note this optimization is not strictly correct,
but is possible.  See comments in the ifu source code for details.

5726b5b640 Added support for logic memory in the IFU and LSU. This disables the bus interface. Peripherals do not work. Also requires using testbench-harvard.sv. I hope to merge this testbench with the main testbench.sv soon. 2022-01-13 22:21:43 -06:00

654a33bf92 Fixed bug in the lsu's write back data. If an AMO was uncached it would not be corrected executed because the write data to the bus would not include the amoalu. 2022-01-12 17:41:39 -06:00

6eb2f37ce4 Possible fix for the TrapM DTLBMiss suppression. 2022-01-12 14:17:16 -06:00
Ross Thompson
6b483e621d If a trap occurs concurrent with a I/DTLB miss the interlock fsm incorrectly goes into the states to handle the TLB miss.
This commit fixes this bug by keeping the interlock fsm in the T0_READY state on TrapM.

796316495d Hack "fix" to prevent interrupt from occuring during an integer divide.
This is not the desired solution but will allow continued debuging of linux.
