Abstract
Description
図3はIC300上のJTAGピン数とIC300およびJTAGコントローラ100間のJTAGバス信号接続数を減らすための本開示の方法を示す。本開示に示すIC300等は、限定はしないが、マイクロコントローラIC、マイクロプロセッサIC、デジタル信号プロセッサIC、混合信号IC、FPGA/CPLDIC、ASIC、システム・オン・チップIC、周辺IC、ROMメモリIC、またはRAMメモリICを含む任意タイプの集積回路を表すことができる。図3において、JTAGコントローラ100はTDO,TMS,CKIN,TDI,およびTRST信号を介してパラレル・ツー・シリアルコントローラ(PSC)にインターフェイスされる。PSC302はJTAGコントローラ100とは別個の回路であり、あるいはPSC302とJTAGコントローラ100を統合して新しいJTAGコントローラ304を形成することができる。PSC302はデータI/O(DIO)信号308およびクロック(CLK)信号310を含むバスを介してIC300内のシリアル・ツー・パラレルコントローラ(SPC)回路306にインターフェイスされる。SPC306はTDI,TMS,TCK,TDO,およびTRST信号を介してIC300内のタップドメイン104にインターフェイスされる。図16−20について後述するように、CLK信号310はJTAGコントローラ100に関連するクロックソース、IC300に関連するクロックソース、またはJTAGコントローラ100またはIC300に関連するクロックソースにより駆動することができる。
DIOがハイであれば、入力回路1102および1108は、それぞれ、JTAGコントローラ100およびSPC306へハイを入力する。
DIOがローであれば、入力回路1102および1108は、それぞれ、JTAGコントローラ100およびSPC306へローを入力する。
DIOが中間レベルでPSC302からのOUT信号がローであれば、入力回路1102はタップドメイン104がTDO上にハイを出力してDIO上に中間レベルを生じていることを知る。したがって、入力回路1102はJTAGコントローラ100のTDI入力にハイを入力する。
DIOが中間レベルでPSC302からのOUT信号がハイであれば、入力回路1102はタップドメイン104がTDO上にローを出力してDIO上に中間レベルを生じていることを知る。したがって、入力回路1102はJTAGコントローラ100のTDI入力にローを入力する。
DIOが中間レベルでタップドメイン104からのTDO信号がローであれば、入力回路1108はPSC302がOUT上にハイを出力してDIO上に中間レベルを生じていることを知る。したがって、入力回路1108はSPC306のIN入力にハイを入力する。
DIOが中間レベルでタップドメイン104からのTDO信号がハイであれば、入力回路1108はPSC302がOUT上にローを出力してDIO上に中間レベルを生じていることを知る。したがって、入力回路1108はSPC306のIN入力にローを入力する。
