Abstract
Description
特許文献1には、関連する技術として、システムの中断前の揮発性メモリの記憶状態、周辺デバイスのレジスタ値、及び、プロセッサのレジスタ値を表すデータを不揮発性メモリに格納し、システムの起動時にOS(Operating System)はカーネル機能によって不揮発性メモリに格納したデータを用いてシステムの中断前の状態を再現することで、情報処理システムを直ちに初期化する技術が記載されている。
そのため、情報処理システムが起動する際に、レジスタを備える周辺デバイスを直ちに初期化することのできる技術が求められている。
情報処理システムは、情報処理システムが起動する際に、スナップショットイメージ情報とレジスタを備える非標準デバイスの初期設定データとを含むデータを、レジスタのアドレスと同一のアドレスの揮発性メモリのメモリ領域へ書き込む処理を行う。こうすることで、情報処理システムが起動する際に、揮発性メモリにおいてスナップショットイメージ情報が再現されると同時に、レジスタに初期設定データが書き込まれる。したがって、スナップショットイメージ情報が揮発性メモリに書き込まれ、標準デバイスが動作可能な状態になるのとほぼ同時に、非標準デバイスは、動作可能な状態となる。
このように、情報処理システムによって、情報処理システムが起動する際に、レジスタを備える周辺デバイスを直ちに初期化することができる。
情報処理システムは、揮発性メモリとレジスタの両方に、アドレスと書込みデータとを入力する。そのため、情報処理システムは、揮発性メモリとレジスタのそれぞれにおいて同一のアドレスを示すメモリ領域に同一の書込みデータが書き込む。こうすることで、情報処理システムは、同一のアドレスを示すメモリ領域において、揮発性メモリとレジスタとで同期をとることができる。
情報処理システムは、揮発性メモリとレジスタの両方に共通するアドレスからデータを読み出す場合、レジスタから書込みデータを取得する。そして、情報処理システムは、レジスタから取得した読出しデータに対応するアドレスと同一のアドレスの揮発性メモリのメモリ領域に読出しデータを書き込む。こうすることで、情報処理システムは、同一のアドレスを示すメモリ領域において、揮発性メモリとレジスタとで同期をとることができる。
情報処理システムは、揮発性メモリとレジスタの両方に共通するアドレスからデータを読み出す場合、揮発性メモリから書込みデータを取得する。そして、情報処理システムは、揮発性メモリから取得した読出しデータに対応するアドレスと同一のアドレスのレジスタのメモリ領域に読出しデータを書き込む。こうすることで、情報処理システムは、同一のアドレスを示すメモリ領域において、揮発性メモリとレジスタとで同期をとることができる。
情報処理システムによる情報処理方法は、揮発性メモリとレジスタの両方に共通するアドレスからデータを読み出す場合、レジスタから書込みデータを取得する。そして、情報処理システムによる情報処理方法は、レジスタから取得した読出しデータに対応するアドレスと同一のアドレスの揮発性メモリのメモリ領域に読出しデータを書き込む。こうすることで、情報処理システムによる情報処理方法は、同一のアドレスを示すメモリ領域において、揮発性メモリとレジスタとで同期をとることができる。
(情報処理システムの構成)
以下、本発明の一実施形態による情報処理システムの構成について説明する。
本発明の一実施形態による情報処理システム1は、図1に示すように、電源10、CPU(Central Processing Unit)20、標準デバイス30、非標準デバイス40(レジスタを備える周辺デバイスの一例)、メモリ50(揮発性メモリの一例)、ストレージ60、セレクタ70を備える。
CPU20は、セレクタ70を介して、メモリ50及びレジスタ401の少なくとも一方との間でデータの読み書きを行う。CPU20は、図2に示すように、adr端子、wreq端子、wdata端子、rreq端子、rdata端子、rvalid端子を備える。adr端子は、メモリ50及びレジスタ401の少なくとも一方についての読み出しまたは書き込み時のアドレスを出力する端子である。wreq端子は、メモリ50及びレジスタ401の少なくとも一方へ書込みを指示する信号を出力する端子である。wdata端子は、wreq端子が書込みを指示する信号を出力したときに書き込むデータを出力する端子である。rreq端子は、メモリ50及びレジスタ401の少なくとも一方へ読出しを指示する信号を出力する端子である。rdata端子は、rreq端子がメモリ50及びレジスタ401の少なくとも一方へ読出しを指示する信号を出力したときに読み出されたデータを受ける端子である。rvalid端子は、rdata端子から受けるデータ(すなわち読み出されたデータ)を特定する信号である。
セレクタ70は、図2に示すように、CPU20、メモリ50、レジスタ401のそれぞれに接続される。セレクタ70は、T1端子、T2端子、T3端子、T4端子、T5端子、T6端子、T7端子、T8端子、T9端子、T10端子、T11端子、T12端子、T13端子、T14端子、T15端子、T16端子、T17端子、T18端子を備える。T1端子は、adr端子に接続される。T2端子は、wreq端子に接続される。T3端子は、wdata端子に接続される。T4端子は、rreq端子に接続される。T5端子は、rdata端子に接続される。T6端子は、rvalid端子に接続される。T7端子は、mem_adr端子に接続される。T8端子は、mem_wreq端子に接続される。T9端子は、mem_wdataに接続される。T10端子は、mem_rreq端子に接続される。T11端子は、mem_rdata端子に接続される。T12端子は、mem_rvalid端子に接続される。T13端子は、reg_adr端子に接続される。T14端子は、wreg端子に接続される。T15端子は、reg_wdataに接続される。T16端子はreg_rreq端子に接続される。T17端子は、reg_rdata端子に接続される。T18端子は、reg_rvalid端子に接続される。
具体的には、例えば、T1端子にメモリ50とレジスタ401とが有する同一のアドレスが入力され、T2端子に書込みを指示する信号が入力された場合、セレクタ70は、T1端子に入力されたアドレスをT7端子とT13端子の両方から出力する。また、セレクタ70は、T2端子に入力された書込みを指示する信号を、T8端子とT14端子の両方から出力する。また、セレクタ70は、T3端子に入力されたデータをT9端子とT15端子の両方に出力する。
次に、本発明の一実施形態による情報処理システム1の処理について説明する。
ここでは、図3(a)~(d)に示す4つの場合について、情報処理システム1の処理の処理を説明する。
図3(a)に示すメモリ50へのデータの書き込み、すなわち、レジスタ401のアドレスとは異なるメモリ50のアドレス(例えば、図3に示すアドレス“m1000”)のメモリ領域へのデータ“1234”の書き込みについて図4に示す処理フローを用いて説明する。
図3(b)に示すレジスタ401へのデータの書き込み、すなわち、レジスタ401のアドレスと同一のメモリ50のアドレス(例えば、図3に示すアドレス“m9000”)のメモリ領域へのデータ“5678”の書き込みについて図5に示す処理フローを用いて説明する。
CPU20は、adr端子からT1端子へアドレス“m9000”を出力する(ステップS11)。また、CPU20は、wdata端子からT3端子へデータ“5678”を出力する(ステップS12)。そして、CPU20は、wreq端子からT2端子へ書込みを指示する“Lowレベルの信号”を出力する(ステップS13)。
図3(c)に示すメモリ50からのデータの読み出し、すなわち、レジスタ401のアドレスとは異なるメモリ50のアドレス(例えば、図3に示すアドレス“m1000”)のメモリ領域からのデータ“1234”の読み出しについて図6に示す処理フローを用いて説明する。
CPU20は、adr端子からT1端子へアドレス“m1000”を出力する(ステップS31)。また、CPU20は、rreq端子からT4端子へ読出しを指示する“Lowレベルの信号”を出力する(すなわち、読出しを指示する信号がアサートされる)(ステップS32)。
メモリ50は、セレクタ70から、アドレス“m1000”、読出しを指示する“Lowレベルの信号”を受ける。メモリ50は、読出しを指示する“Lowレベルの信号”に応じて、アドレス“m1000”のメモリ領域のデータ“1234”をmem_rdata端子から端子11へ出力する(ステップS35)。また、メモリ50は、読出しを指示する“Lowレベルの信号”に応じて、mem_rvalid端子からT12端子へデータ“1234”を特定する“Lowレベルの信号”を出力する(ステップS36)。
CPU20は、rvalid端子が“Lowレベルの信号”を受けている間にrdata端子が受けたデータ“1234”を読み出したデータとして取得する(ステップS39)。
図3(d)に示すレジスタ401からのデータの読み出し、すなわち、メモリ50において同一のアドレスが存在するレジスタ401のアドレス(例えば、図3に示すアドレス“m8000”)のメモリ領域からのデータ“9876”の読み出しについて図7に示す処理フローを用いて説明する。
メモリ50は、書込みを指示する“Lowレベルの信号”を受ける。メモリ50は、書込みを指示する信号に応じて、セレクタ70から受けたアドレス“m8000”のメモリ領域にデータ“9876”を書き込む(ステップS52)。
以上、本発明の一実施形態による情報処理システム1について説明した。
本発明の一実施形態による情報処理システム1では、CPU20は、アドレスと、そのアドレスへデータを書き込むことを指示する書込み指示信号またはそのアドレスからデータを読み出すことを指示する読出し指示信号とをセレクタ70に出力する。セレクタ70は、アドレス、書込み指示信号及び読出し指示信号に応じて、CPU20から入力されたデータの出力先が決定されるようにハードウェアで構成される。メモリ50は、セレクタ70が出力する信号に基づいて、情報処理システム1が起動する際に、スナップショットイメージ情報とレジスタ401を備える非標準デバイス40の初期設定データとを含むデータを記憶する。レジスタ401は、メモリ50が初期設定データを記憶するメモリ領域のアドレスと同一のアドレスを有する。
このように、情報処理システム1によって、情報処理システム1が起動する際に、レジスタ401を備える非標準デバイス40を直ちに初期化することができる。
なお、本発明の別の実施形態による情報処理システム1において、レジスタ401は、書き込み及び読み出しの両方が可能であるものとして説明した。しかしながら、レジスタ401の中には、書き込みのみが可能であるものも存在する。
レジスタ401が書き込みのみ可能な場合、上述の(レジスタ401からのデータの読み出し)におけるレジスタ401とメモリ50とを入れ替え、メモリ50からデータを読み出し、読み出したデータをレジスタ401に書き込む処理を、(レジスタ401からのデータの読み出し)における処理と同様に行うことで、メモリ50とレジスタ401のデータを同期することができる。また、CPU20は、レジスタ401が記憶すべきデータをメモリ50から読み出すことができる。
図8は、少なくとも1つの実施形態に係るコンピュータの構成を示す概略ブロック図である。
コンピュータ5は、図8に示すように、CPU6、メインメモリ7、ストレージ8、インターフェース9を備える。
例えば、上述の標準デバイス30、非標準デバイス40、その他の制御装置のそれぞれは、コンピュータ5に実装される。そして、上述した各処理部の動作は、プログラムの形式でストレージ8に記憶されている。CPU6は、プログラムをストレージ8から読み出してメインメモリ7に展開し、当該プログラムに従って上記処理を実行する。また、CPU6は、プログラムに従って、上述した各記憶部に対応するメモリ領域をメインメモリ7に確保する。
