SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill allows for precise control and management of PSX timers, enabling developers to synchronize tasks with timer interrupts, handle vsync timing, and perform frame counting.

Core Features & Use Cases

  • Timer Configuration: Set up and manage timer registers, including current value, counter mode, and target value.
  • Dotclock/Hblank Sources: Utilize dotclock and hblank sources for timer synchronization.
  • Reset and Wrap Behavior: Control reset and wrap behavior for timers to ensure correct timing and interrupt handling.
  • Use Case: Developers can use this Skill to synchronize rendering with timers for accurate frame rendering and timing.

Quick Start

Set up the timers for frame counting by using the timers skill to configure timer 0 with a system clock source and enable the counter mode for Hblank interrupts.

Frequently Asked Questions about timers

FAQPage Schema
How do I configure PlayStation 1 timer registers for precise hardware synchronization?▼

Configure PlayStation 1 timer registers by setting current value, counter mode, and target value to control hardware synchronization. This allows detailed management of timer behavior for applications requiring precise timing with hardware counters.

Can I use dotclock and hblank sources for PSX timer synchronization?▼

Yes, you can utilize dotclock and hblank sources for PSX timer synchronization. These clock sources enable accurate timer interrupts and synchronization with display rendering events like vsync.

What is the best way to handle vsync timing and frame counting on the PSX?▼

Handle vsync timing and frame counting by configuring a PSX timer with a system clock source and enabling counter mode for Hblank interrupts. This synchronizes rendering with timers for accurate frame rendering.

Do I need knowledge of CPU interrupt handling to manage PSX timers?▼

Yes, managing PSX timers requires access to CPU timer registers and knowledge of interrupt handling in the PlayStation 1 architecture. This prerequisite knowledge is necessary to correctly configure interrupt modes and register values.

How do I control reset and wrap behavior for PSX hardware counters?▼

Control reset and wrap behavior for PSX hardware counters by configuring the counter mode settings in the timer registers. This ensures correct timing and proper interrupt handling when counters reach their target values.
