2023-01-11 | For NS16550 UART, poll stdin less oftentmp | Andrew Waterman | 2 | -1/+12 | |
On my Mac Mini, calling `poll()` on stdin takes around 10 us, and we are invoking it every 20 us or so. Reduce the frequency of polling by 16x when not actively receiving data, thereby reducing the fraction of time spent in `poll()` to a trivial amount. | |||||
2023-01-11 | Run Spike and HTIF in a single thread, rather than two | Andrew Waterman | 2 | -31/+14 | |
The two-thread approach was originally motivated by making Spike look as similar as possible to other HTIF targets. But we can get the same semantics without threading by running the simulator inside of the HTIF host's idle loop instead of performing a context switch. This was motivated by speeding up the simulator on Mac OS (it's worth around 20% because using pthread condition variables to force strict alternation is very slow). But I think it also simplifies the control flow enough to justify it on that basis, too. | |||||
