Trait VideoBus 

Source 
pub trait VideoBus: RdramBus {
    // Provided method
    fn raise_dp_interrupt(&mut self) { ... }
}
Expand description

The narrow bus the RDP sees.

RDRAM access (for the framebuffer + texture fetches) plus the DP-interrupt-raise hook. Extends RdramBus (RustyNES’s PpuBus analog) with the IRQ notify the rasterizer needs on SYNC_FULL / DP-done.

Provided Methods§

Source

fn raise_dp_interrupt(&mut self)

Raise the DP (RDP-done) interrupt on the MI. Default no-op for ad-hoc test buses; rustyn64-core sets the live MI_INTR.dp line.
