DoGav Systems announces coalescing microcode module for the PowerQUICC II

Coalescing is a feature of the PowerQUICC II Pro and PowerQUICC III families aimed at minimizing the overhead associated with interrupt handling.

When a driver is designed to handle receive (Rx) or transmit (Tx) events as soon as they occur in order to match real-time requirements, it may severely affect the overall system performance, particularly in a heavy traffic environment. This is due to the overhead associated with the frequent accessing and exiting the interrupt handler.

This coalescing microcode module offers similar functionality for the PowerQUICC II family. It enables the system to continue to maintain real-time performance, whilst reducing the cost of the context switching by sharing the overhead associated with interrupts between a configurable number of events.

Key features:

• Implemented for PowerQUICC II FCC Ethernet receiver
• Dramatically reduces the host Interrupt overhead
• Parameters can be dynamically updated by the user application
• Extensive statistics gathering
• Very small footprint (negligible impact on the CPM activities)
• Easily integrated into existing user applications. No code modification is required, except some additional initialization code
• Supports all PowerQUICC II versions
