* difftest: use DPI-C to refactor difftest In this commit, difftest is refactored with DPI-C calls. There're a few reasons: (1) From Verilator's manual, DPI-C calls should be more efficient than accessing from dut_ptr. (2) DPI-C is cross-platform (Verilator, VCS, ...) (3) difftest APIs are splited from emu.cpp to possibly support more backend platforms (NEMU, Spike, ...) The performance at this commit is quite slower than the original emu. Performance issues will be fixed later. * [WIP] SimTop: try to use 'XSTop' as soc * CircularQueuePtr: ues F-bounded polymorphis instead implict helper * Refactor parameters & Clean up code * difftest: support basic difftest * Support diffetst in new sim top * Difftest; convert recode fmt to ieee754 when comparing fp regs * Difftest: pass sign-ext pc to dpic functions && fix exception pc * Debug: add int/exc inst wb to debug queue * Difftest: pass sign-ext pc to dpic functions && fix exception pc * Difftest: fix naive commit num limit Co-authored-by: NYinan Xu <xuyinan1997@gmail.com> Co-authored-by: NWilliam Wang <zeweiwang@outlook.com>

XSPerfAccumulate: sum up performance values. XSPerfHistogram: count the occurrence of performance values, split them into bins, so that we can estimate their distribution. XSPerfMax: get max of performance values.

* Replacement: change state in way method. * State change is also needed when miss occurs, otherwise we will choose a way that has been just refilled into cache as the victim. * Optimize ctrlblock timing (#620) * CtrlBlock: delay exception flush for 1 cycle * CtrlBlock: delay load replay for 1 cycle * roq: delay wb from exu for one clock cycle to meet timing * CtrlBlock: fix pipeline bug between decode and rename Co-authored-by: NYinan Xu <xuyinan1997@gmail.com> * L1plusCache: use plru replacement policy. * ICache: fix mmio bugs 1. MMIO cut helper uses packet align logic 2. still send req to uncache when flush * ICache: change packet from mmio use packet align as the mem * IntrUncache: fix state bug state will change into s_invalid and get stuck * fix Registers that not being initiated
