1894afd0d8 Changed name of LSU's FetchCount to WordCount. This better reflex the dual usage as fetch and eviction counters.
Fixed bug with the uncached memory operations.  The periph tests still do not pass.  They enter into what seems an intentional infinite loop.  Then a uart interrupt jumps into an ISR but the ISR returns back to the loop.

74d636cb53 First cut at moving the dcache bus interface into the LSU.
Regression test does not run and there is a lot of cleanup to do.

7fe70c3cc6 Removed the fault state from the hptw. Now writing TLB faults into the I/DTLBs. This has two advantages.
1: It simplifies the interactions between the caches and the hptw.
2: instruction page faults are fetched 3 times, caching them in the ITLB speeds up this process.

There are two downsides.
1: Pollute the TLBs with not very relavent translations
2: Have to compute the misalignment.  This can be cached in the TLB which only costs 1 flip flop
   for each TLB line.

8416cae3fe Fixed Type 5b interaction between dcache and hptw.
This is a load concurrent with ITLBMiss.

c9291655da Fixed bug most of the bugs related to the dcache changes, but the mmu tests don't pass. 2021-12-19 16:12:31 -06:00

a445bedcd2 Modified the icache memory to read using the virtual (non physical) address in the PCNextF stage.
This allows recovering from an ITLBMiss to be 1 cycle after and simplifies the hptw slightly.
