2012-08-28Clock: Add a Cycles wrapper class and use where applicableAndreas Hansson
This patch addresses the comments and feedback on the preceding patch that reworks the clocks and now more clearly shows where cycles (relative cycle counts) are used to express time. Instead of bumping the existing patch I chose to make this a separate patch, merely to try and focus the discussion around a smaller set of changes. The two patches will be pushed together though. This changes done as part of this patch are mostly following directly from the introduction of the wrapper class, and change enough code to make things compile and run again. There are definitely more places where int/uint/Tick is still used to represent cycles, and it will take some time to chase them all down. Similarly, a lot of parameters should be changed from Param.Tick and Param.Unsigned to Param.Cycles. In addition, the use of curTick is questionable as there should not be an absolute cycle. Potential solutions can be built on top of this patch. There is a similar situation in the o3 CPU where lastRunningCycle is currently counting in Cycles, and is still an absolute time. More discussion to be had in other words. An additional change that would be appropriate in the future is to perform a similar wrapping of Tick and probably also introduce a Ticks class along with suitable operators for all these classes.
2011-06-19inorder: handle serializing instructionsKorey Sewell
including IPR accesses and store-conditionals. These class of instructions will not execute correctly in a superscalar machine
2011-04-15includes: sort all includesNathan Binkert
2011-02-18inorder: recognize isSerializeAfter flagKorey Sewell
keep track of when an instruction needs the execution behind it to be serialized. Without this, in SE Mode instructions can execute behind a system call exit().
2011-02-04inorder: multi-issue branch resolutionKorey Sewell
Only execute (resolve) one branch per cycle because handling more than one is a little more complicated
2010-06-24inorder: cleanup virtual functionsKorey Sewell
remove the annotation 'virtual' from function declaration that isnt being derived from
2010-06-24inorder: exe_unit_stats for resolved branchesKorey Sewell
2010-06-23inorder-stats: add instruction type statsKorey Sewell
also, remove inst-req stats as default.good for debugging but in terms of pure processor stats they aren't useful
2010-01-31inorder: object cleanup in destructorsKorey Sewell
2010-01-31inorder: add execution unit statsKorey Sewell
2009-03-05stats: Fix all stats usages to deal with template fixesNathan Binkert
2009-02-10InOrder: Import new inorder CPU model from MIPS.Korey Sewell
This model currently only works in MIPS_SE mode, so it will take some effort to clean it up and make it generally useful. Hopefully people are willing to help make that happen!
