Low-Cost DDR3 Decode and Analysis with Portable Logic Analyzers
应用文章
As embedded systems take on more sophisticated applications, they also require advanced external memory systems, such as DDR3, in order to offer adequate throughput. At times it can be helpful to see memory activity and perform some level of memory analysis in order to properly validate and debug a prototype system. New options now allow this at inexpensive price points compared to previous solutions. New general-purpose, low-cost logic analyzers, like the 16850 Series shown in Figure 1, offer the performance required for such measurements as well as related analysis tools to provide this kind of insight.
