spike-vp

A proof of concept virtual platform that use Spike as the ISS, and use VCML as the SystemC library.

Updates

2024/2/4

Optimize the memory access strategy of Spike for non-dmi access. With this optimization, it takes 160 seconds to boot the linux kernel. It's nine times faster than the original memory access strategy.

---

2024/2/3

Add Spike L1DCache and L1ICache simulation. Add a config for running the dhrystone, the dhrystone binary is from the chipyard project.

---

2023/8/14

If the memory simulation support DMI, it takes 1 minute to boot the linux kernel.

---

2023/8/9

If we don't use dmi, it takes 25 minutes to boot the linux kernel.
