Codelets

23.10Performance Profiling Codelet (IxPerfProfAccCodelet)

IxPerfProfAccCodelet is a useful utility that demonstrates how to access performance related data provided by IxPerfProfAcc. The codelet provides an interface to view north, south, and SDRAM bus activity, event counting and idle cycles from the Intel XScale core PMU and other performance attributes of the processor.

Note: IxPerfProfAccCodelet has not been modified to support the Intel® IXP46X product line processors at this time.

23.11Time Sync Codelet (IxTimeSyncAccCodelet)

This codelet shows how to use some of the IxTimeSyncAcc API functions to utilize the following features of the IEEE 1588 unit available on the Intel® IXP46X product line processors:

•How to configure a channel to operate in master or slave mode.

•How to set the frequency scaling value.

•How to set and get system time.

•How to setup target time in interrupt mode.

•How to enable and disable the target time interrupt.

•How to make use of polled mode Rx and Tx PTP message timestamps for several NPE configurations.

An external device, such as a SmartBits*, may be used to generate PTP messages and transmit to the NPE channels.

23.12USB RNDIS Codelet (IxUSBRNDIS)

The IxUSBRNDIS codelet is a sample driver implementation of an RNDIS client.

RNDIS (Remote Network Driver Interface Specification) is a specification for Ethernet-like interface compatible with Microsoft* operating systems. This codelet allows a properly configured platform based upon Intel® IXP4XX Product Line of Network Processors and IXC1100 Control Plane Processor, running VxWorks or Linux to communicate IP traffic over USB to a Microsoft* Windows* system.
