48.2. Resource Usage and Performance

This section lists the resource usage and performance data for supported devices when operating the Half-Rate Bridge with a full-rate DDR SDRAM high-performance memory controller.

Using the Half-Rate Bridge with a full-rate DDR SDRAM high-performance memory controller results an average of 48% performance improvement over a system using a half-rate DDR SDRAM high-performance memory controller in a series of embedded applications. The performance improvement is 62.2% based on the Dhrystone benchmark, and 87.7% when accessing memory bypassing the cache. For memory systems that use the Half-Rate bridge in conjunction with DDR2/3 High Performance Controller, the data throughput is the same on the Half-Rate Bridge host and agent interfaces. The decrease in memory latency on the Half-Rate Bridge agent interface results in higher performance for the processor.

The table below shows the resource usage for Stratix® II and Stratix® III devices in the Intel® Quartus® Prime software with a data width of 16 bits, an address span of 24 bits.
