Application Specific Memory Access, Reuse and Reordering for SDRAM
نویسندگان
چکیده
The efficient use of bandwidth available on an external SDRAM interface is strongly dependent on the sequence of addresses requested. On-chip memory buffers can make possible data reuse and request reordering which together ensure bandwidth on an SDRAM interface is used efficiently. This paper outlines an automated procedure for generating an application-specific memory hierarchy which exploits reuse and reordering and quantifies the impact this has on memory bandwidth over a range of representative benchmarks. Considering a range of parameterized designs, we observe up to 50x reduction in the quantity of data fetched from external memory. This, combined with reordering of the transactions, allows up to 128x reduction in the memory access time of certain memory-intensive benchmarks.

Synchronous DRAM (SDRAM) has become a mainstream memory of choice in design due to its speed, burst access and pipeline features. For high-end applications using processors, the interface to the SDRAM is supported by the processor’s built-in peripheral module. However, for other applications, the system designer must design a controller to provide proper commands for SDRAM initialization, read/...

The application of the synchronous dynamic random access memory (SDRAM) has gone beyond the scope of personal computers for quite a long time. It comes into hand whenever a big amount of low price and still high speed memory is needed. Most of the newly developed stand alone embedded devices in the field of image, video and sound processing take more and more use of it. The big amount of low pr...
