A42MX09-3VQG100 Working Principle

The A42MX09-3VQG100 FPGA uses a combination of hardware and software to implement the design of an embedded system. The hardware is configured and controlled by a register-transfer-level (RTL) description of the system. This is done using special design files that are loaded onto the device at power-up. The RTL code is compiled into the device-specific logic elements and the connection of specified components is done via internal “nets”.

During operation, the device reads and interprets the RTL design code, using this to control the behavior of the system. Data flow between the main processor and the external peripherals is managed by extensive memory and busing structures within the FPGA. Data can be transferred between the main processor and the peripheral devices in either a parallel or serial manner, depending on the design.

The A42MX09-3VQG100 also incorporates high-performance logic blocks that allow the device to operate at increased clock frequencies – up to 150 MHz. It features four embedded high-performance memories that can serve as either instruction memories for the processor or as program memories for the device’s firmware. In addition, the device has a wide range of general I/O peripherals including UARTs, timers, and interrupts, which can be used to implement custom peripherals or integrate peripheral devices directly into the design.

Conclusion

The A42MX09-3VQG100 FPGA from Actel Corporation is a highly versatile device designed for embedded systems. It features a wide range of features, including 32-bit wide memory interfaces, high-speed bus ports, on-chip memory buses, 10/100 Ethernet MAC block, and low-voltage differential I/O blocks. It also ontains comprehensive integrated peripherals and uses a combination of hardware and software to implement the design of an embedded system.
