It use the perfect switch and a 317054Snate@binkert.org * Throttle object to control and bandwidth and timing *only for the 327054Snate@binkert.org * output port*. So here we have un-realistic modelling, since the 337054Snate@binkert.org * order of PerfectSwitch and Throttle objects get woke up affect the 347054Snate@binkert.org * message timing. A more accurate model would be having two set of 357054Snate@binkert.org * system states, one for this cycle, one for next cycle. And on the 367054Snate@binkert.org * cycle boundary swap the two set of states. 376145Snate@binkert.org */ 386145Snate@binkert.org 397054Snate@binkert.org#ifndef __MEM_RUBY_NETWORK_SIMPLE_SWITCH_HH__ 407054Snate@binkert.org#define __MEM_RUBY_NETWORK_SIMPLE_SWITCH_HH__ 416145Snate@binkert.org 427002Snate@binkert.org#include <iostream> 437454Snate@binkert.org#include <vector> 447002Snate@binkert.org 456154Snate@binkert.org#include "mem/ruby/common/Global.hh" 466145Snate@binkert.org 476145Snate@binkert.orgclass MessageBuffer; 486145Snate@binkert.orgclass PerfectSwitch; 496145Snate@binkert.orgclass NetDest; 506145Snate@binkert.orgclass SimpleNetwork; 516145Snate@binkert.orgclass Throttle; 526145Snate@binkert.org 537054Snate@binkert.orgclass Switch 547054Snate@binkert.org{ 557054Snate@binkert.org public: 567054Snate@binkert.org Switch(SwitchID sid, SimpleNetwork* network_ptr); 577054Snate@binkert.org ~Switch(); 586145Snate@binkert.org 597454Snate@binkert.org void addInPort(const std::vector<MessageBuffer*>& in); 607454Snate@binkert.org void addOutPort(const std::vector<MessageBuffer*>& out, 617054Snate@binkert.org const NetDest& routing_table_entry, int link_latency, 627054Snate@binkert.org int bw_multiplier); 637054Snate@binkert.org const Throttle* getThrottle(LinkID link_number) const; 647454Snate@binkert.org const std::vector<Throttle*>* getThrottles() const; 657054Snate@binkert.org void clearRoutingTables(); 667054Snate@binkert.org void clearBuffers(); 677054Snate@binkert.org void reconfigureOutPort(const NetDest& routing_table_entry); 686145Snate@binkert.org 697054Snate@binkert.org void printStats(std::ostream& out) const; 707054Snate@binkert.org void clearStats(); 717054Snate@binkert.org void printConfig(std::ostream& out) const; 726145Snate@binkert.org 737054Snate@binkert.org void print(std::ostream& out) const; 746145Snate@binkert.org 757054Snate@binkert.org private: 767054Snate@binkert.org // Private copy constructor and assignment operator 777054Snate@binkert.org Switch(const Switch& obj); 787054Snate@binkert.org Switch& operator=(const Switch& obj); 796145Snate@binkert.org 807054Snate@binkert.org PerfectSwitch* m_perfect_switch_ptr; 818259SBrad.Beckmann@amd.com SimpleNetwork* m_network_ptr; 827454Snate@binkert.org std::vector<Throttle*> m_throttles; 837454Snate@binkert.org std::vector<MessageBuffer*> m_buffers_to_free; 847054Snate@binkert.org SwitchID m_switch_id; 856145Snate@binkert.org}; 866145Snate@binkert.org 877054Snate@binkert.orginline std::ostream& 887054Snate@binkert.orgoperator<<(std::ostream& out, const Switch& obj) 896145Snate@binkert.org{ 907054Snate@binkert.org obj.print(out); 917054Snate@binkert.org out << std::flush; 927054Snate@binkert.org return out; 936145Snate@binkert.org} 946145Snate@binkert.org 957054Snate@binkert.org#endif // __MEM_RUBY_NETWORK_SIMPLE_SWITCH_HH__ 96
