This document explains the advantages of Actel FPGA's power‑up immediate operation (LAPU) for faster system initialization and reliable performance.
The note introduces the concept of power‑up immediate operation (LAPU) and presents a classification system that defines 0‑level, 1‑level and 2‑level LAPU devices. It describes how Actel FPGA devices fit into each level and the impact on system design.
Key benefits include dramatically reduced initialization time, the ability of non‑volatile FPGA to operate before power‑up, and speed advantages of Flash‑based devices over SRAM‑based parts. The document also lists various application examples such as lighting, motor control, and industrial automation where LAPU can improve reliability and efficiency. This manual is written in Chinese.
| 1‑level LAPU devices | Require configuration download |
|---|---|
| Flash FPGA speed advantage | Up to 4000× faster than SRAM FPGA |
| Non‑volatile FPGA operation | Can operate before power‑up |
LAPU means "Power‑up Immediate Operation", describing devices that can function during the power‑up phase.
Flash FPGA can be up to 4000 times faster than SRAM FPGA in power‑up operation.
It shortens system initialization time and allows critical functions to start immediately, improving efficiency and reliability.
