The RISC-V Platform-Level Interrupt Controller (PLIC) by IQonIC Works is a sophisticated, configurable interrupt manager designed to support systems with a vast array of interrupt sources. Adhering to RISC-V specifications, it ensures efficient delivery of interrupts to multiple processor targets, whether in single or multiprocessor architectures. Its capabilities extend to managing up to 1023 interrupt sources across varying priority levels and target configurations.
PLIC offers exceptional flexibility through its AHB-Lite interfacing, allowing streamlined access for setting priorities, enables, and handling interrupt claims. Its asynchronous request handling and comprehensive security features ensure dependable and secure interrupt allocation, supporting both synchronous and asynchronous signals. The capability to enable interrupts for multiple targets facilitates efficient resource sharing.
In complex systems, the PLIC provides seamless integration with shared bus structures, correlating interrupt requests with processor execution contexts effectively. This integration contributes to a reduction in response latency and boosts overall system reliability. By leveraging IQonIC Works' PLIC, developers can ensure high-performance interrupt management crucial for modern, versatile computing environments.
