The RISC-V Timer IP from IQonIC Works offers a collection of timers that adhere to the RISC-V standard machine timer specification, providing essential timing solutions for embedded systems. These timers are versatile, supporting simple setups that count processor-clock cycles without involving clock-domain crossing (CDC), and more complex arrangements suitable for low-power applications, where the system clock might be gated off.
For such low-power use cases, the timer can instead count cycles from a low-frequency, always-on clock like a 32kHz oscillator, making it ideal for applications where energy efficiency is paramount. Different timer variants come with an AHB bus interface for sophisticated systems or an APB interface for more streamlined, simpler bus structures.
The inclusion of an AHB interface in some versions allows integration into systems with layered buses, whereas APB-only options cater to systems with straightforward APB buses. This timer IP suite ensures flexibility and performance for a wide range of design needs in both simple and complex embedded environments.
