1–Product Overview
Adapter Specifications
3 BC0154503-00 B
Adaptive Interrupt Frequency
The adapter driver intelligently adjusts host interrupt frequency based on traffic
conditions to increase overall application throughput. When traffic is light, the
adapter driver interrupts the host for each received packet, minimizing latency.
When traffic is heavy, the adapter issues one host interrupt for multiple,
back-to-back incoming packets, preserving host CPU cycles.
ASIC with Embedded RISC Processor
The core control for the QL45212 Adapter resides in a tightly integrated,
high-performance ASIC. The ASIC includes a RISC processor, which provides the
flexibility to add new features to the card and adapts it to future network
requirements through software downloads. The RISC processor also enables the
adapter drivers to exploit the built-in host offload functions on the adapter as host
operating systems are enhanced to take advantage of these functions.
