2014-05-09	config: Bump DRAM sweep bus speed to match DDR4 config	Andreas Hansson
	This patch bumps the bus clock speed such that the interconnect does not become a bottleneck with a DDR4-2400-x64 DRAM delivering 19.2 GByte/s theoretical max.
2014-03-23	mem: Rename SimpleDRAM to a more suitable DRAMCtrl	Andreas Hansson
	This patch renames the not-so-simple SimpleDRAM to a more suitable DRAMCtrl. The name change is intended to ensure that we do not send the wrong message (although the "simple" in SimpleDRAM was originally intended as in cleverly simple, or elegant). As the DRAM controller modelling work is being presented at ISPASS'14 our hope is that a broader audience will use the model in the future. --HG-- rename : src/mem/SimpleDRAM.py => src/mem/DRAMCtrl.py rename : src/mem/simple_dram.cc => src/mem/dram_ctrl.cc rename : src/mem/simple_dram.hh => src/mem/dram_ctrl.hh
2014-03-23	config: Add a DRAM efficiency-sweep script	Andreas Hansson
	This patch adds a configuration that simplifies evaluation of DRAM controller configurations by automating a sweep of stride size and bank parallelism. It works in a rather unconventional way, as it needs to print the traffic generator stimuli based on the memory organisation. Hence, it starts by configuring the memory, then it prints a traffic-generator config file, and loads it. The resulting stats have one period per data point, identified by the stride size, and the number of banks being used.
