Performance monitors (PMs) for measuring performance in a system and providing a record of transactions performed

摘要

Performance monitors (PMs) are provided in a system to identify the execution time for data being transferred within the system and determine operation parameters of the system based on the rate data is transferred. The operation parameters are then used to configure hardware within the system. The PMs can provide a histogram of the transactions usable to evaluate system performance. The PMs can provide a time line diagram of the transactions to show the specific order the transactions occurred. The PMs can be provided in a multi-port memory controller (MPMC) to monitor the speed of read and write transactions from the MPMC ports, and used to configure logic within the MPMC to maximize the rate of data flow.
