This defines the period which is -// used as the memory channel clock period, the address bus bit time, and the -// memory controller cycle time. -// Assuming a 200 MHz memory channel (DDR-400, which has 400 bits/sec data), -// and a 2 GHz Ruby clock: -MEM_BUS_CYCLE_MULTIPLIER: 10 - -// How many internal banks in each DRAM chip: -BANKS_PER_RANK: 8 - -// How many sets of DRAM chips per DIMM. -RANKS_PER_DIMM: 2 - -// How many DIMMs per channel. (Currently the only thing that -// matters is the number of ranks per channel, i.e. the product -// of this parameter and RANKS_PER_DIMM. But if and when this is -// expanded to do FB-DIMMs, the distinction between the two -// will matter.) -DIMMS_PER_CHANNEL: 2 - -// Which bits to use to find the bank, rank, and DIMM numbers. -// You could choose to have the bank bits, rank bits, and DIMM bits -// in any order; here they are in that order. -// For these defaults, we assume this format for addresses: -// Offset within line: [5:0] -// Memory controller #: [7:6] -// Bank: [10:8] -// Rank: [11] -// DIMM: [12] -// Row addr / Col addr: [top:13] -// If you get these bits wrong, then some banks won't see any -// requests; you need to check for this in the .stats output. -BANK_BIT_0: 8 -RANK_BIT_0: 11 -DIMM_BIT_0: 12 - -// Number of entries max in each bank queues; set to whatever you want. -// If it is too small, you will see in the .stats file a lot of delay -// time spent in the common input queue. -BANK_QUEUE_SIZE: 12 - -// Bank cycle time (tRC) measured in memory cycles: -BANK_BUSY_TIME: 11 - -// This is how many memory address cycles to delay between reads to -// different ranks of DRAMs to allow for clock skew: -RANK_RANK_DELAY: 1 - -// This is how many memory address cycles to delay between a read -// and a write. This is based on two things: (1) the data bus is -// used one cycle earlier in the operation; (2) a round-trip wire -// delay from the controller to the DIMM that did the reading. -READ_WRITE_DELAY: 2 - -// Basic address and data bus occupancy. If you are assuming a -// 16-byte-wide data bus (pairs of DIMMs side-by-side), then -// the data bus occupancy matches the address bus occupancy at -// two cycles. But if the channel is only 8 bytes wide, you -// need to increase this bus occupancy time to 4 cycles. -BASIC_BUS_BUSY_TIME: 2 - -// Latency to returning read request or writeback acknowledgement. -// Measured in memory address cycles. -// This equals tRCD + CL + AL + (four bit times) -// + (round trip on channel) -// + (memory control internal delays) -// It's going to be an approximation, so pick what you like. -// Note: The fact that latency is a constant, and does not depend on two -// low-order address bits, implies that our memory controller either: -// (a) tells the DRAM to read the critical word first, and sends the -// critical word first back to the CPU, or (b) waits until it has -// seen all four bit times on the data wires before sending anything -// back. Either is plausible. If (a), remove the "four bit times" -// term from the calculation above. -MEM_CTL_LATENCY: 12 - -// refresh_period is the number of memory cycles between refresh -// of row x in bank n and refresh of row x+1 in bank n. For DDR-400, -// this is typically 7.8 usec for commercial systems; after 8192 such -// refreshes, this will have refreshed the whole chip in 64 msec. If -// we have a 5 nsec memory clock, 7800 / 5 = 1560 cycles. The memory -// controller will divide this by the total number of banks, and kick -// off a refresh to *somebody* every time that amount is counted -// down to zero. (There will be some rounding error there, but it -// should have minimal effect.) -REFRESH_PERIOD: 1560 - -// tFAW is a DRAM chip parameter which restricts the number of -// activates that can be done within a certain window of time. -// The window is specified here in terms of number of memory -// controller cycles. At most four activates may be done during -// any such sliding window. If this number is set to be no more -// than 4 * BASIC_BUS_BUSY_TIME, it will have no effect. -// It is typical in real systems for tFAW to have no effect, but -// it may be useful in throttling power. Set to zero to ignore. -TFAW: 0 - -// By default, the memory controller uses round-robin to arbitrate -// between ready bank queues for use of the address bus. If you -// wish to add randomness to the system, set this parameter to -// one instead, and it will restart the round-robin pointer at a -// random bank number each cycle. If you want additional -// nondeterminism, set the parameter to some integer n >= 2, and -// it will in addition add a n% chance each cycle that a ready bank -// will be delayed an additional cycle. Note that if you are -// in MEM_FIXED_DELAY mode (see below), MEM_RANDOM_ARBITRATE=1 will -// have no effect, but MEM_RANDOM_ARBITRATE=2 or more will. -MEM_RANDOM_ARBITRATE: 0 - -// The following parameter, if nonzero, will disable the memory -// controller and instead give every request a fixed latency. The -// nonzero value specified here is measured in memory cycles and is -// just added to MEM_CTL_LATENCY. It will also show up in the stats -// file as a contributor to memory_delays_stalled_at_head_of_bank_queue. -MEM_FIXED_DELAY: 0 - -// If instead of DDR-400, you wanted DDR-800, the channel gets faster -// but the basic operation of the DRAM core is unchanged. -// Busy times appear to double just because they are measured -// in smaller clock cycles.
