Because MLE NPAP does not rely on \u201csoft\u201d CPUs nor on external CPUs, MLE NPAP shows very low and deterministic latency. Tradeoff cost vs performance over chip resources. Dataflow is full duplex 128 bits wide using AXI4 Stream. This enables high data throughput without \u201cFPGA bloat\u201d nor timing issues. Control-flow uses AXI4 Lite register interfaces, along with a hardware abstraction layer (HAL), Linux device drivers and Python scripts for MLE NPAP administration. MLE NPAP is intensively tested for performance and interoperability against many other TCP\/UDP\/IPv4 network stacks. MLE NPAP brings its own 10G \/ 25G Low-Latency Ethernet MAC,but can interface with many Ethernet subsystems from the FPGA vendors. MLE NPAP implements a complete TCP\/UDP\/IPv4 stack including functions like ARP, ICMPv4, IGMPv4, DHCP. MLE NPAP is delivered with \u201cSupport IP blocks\u201d including reference designs, design examples for setting MAC addresses and\/or IPv4 addresses and\/or TCP port numbers either from Programmable Logic \/ ASIC or via software running on a (Linux) host, either ARM or x86 based.
