Description
本実施の形態では、本発明の一形態である非同期回路を用いたプログラマブルロジックデバイスについて説明を行う。
まず、プログラマブルロジックデバイスを構成する基本回路について説明を行う。
図3(A)に示す半導体装置20は、半導体装置10を用いてバッファを構成した例である。なお、半導体装置20をHB(ハーフバッファ)と呼ぶ場合がある。半導体装置20は、2つの半導体装置10と、1つのNORゲートから構成される。図3(B)は、半導体装置20をシンボルで表したものである。信号SA、信号E0および信号E1は、半導体装置20の入力信号であり、信号EA、信号S0および信号S1は、半導体装置20の出力信号である。
(1)SA=1のとき、半導体装置20は後段にデータを送信できる状態にある。
(2)SA=0のとき、半導体装置20は後段にデータを送信できない状態にある。
(3)EA=1のとき、半導体装置20は前段からデータを受信できる状態にある。
(4)EA=0のとき、半導体装置20は前段からデータを受信できない状態にある。
図6は、上述の半導体装置20を用いてPLE(プログラマブルロジックエレメント)を構成した例である。図6に示すPLE30は、HB31[1]乃至31[n](nは1以上の整数)と、HB32と、BUF(バッファ)60と、LUT(ルックアップテーブル)40と、トランジスタTr11と、OR回路34とを有する。
図7はLUT40の構成例を示す回路図である。LUT40は、CM(コンフィギュレーションメモリ)50[0]乃至50[m](mは0以上、(2n-1)以下の整数)と、OR回路41[0]乃至41[m]と、AND回路42[0]乃至42[m]と、AND回路43[0]乃至43[m]と、AND回路44[0]乃至44[m]と、を有する。
図8はCM50の回路構成例を示す回路図である。CM50はトランジスタTr12乃至Tr17と、インバータ51と、インバータ52と、を有する。トランジスタTr12およびトランジスタTr15に先述のOSトランジスタを用いることが好ましい。信号WW、CT、B、BBはCM50の入力信号であり、信号D、DBはCM50の出力信号である。
図9はBUF60の構成例を示す回路図である。BUF60は、信号OUT0を信号OUT0[1]乃至OUT0[3]に分割し、信号OUT1を信号OUT1[1]乃至OUT1[3]に分割する機能を有する。また、BUF60は回路61を有し、信号OUTA[1]乃至OUTA[3]を信号OUTAに統合する機能を有する。回路61は、図2(C)に示す半導体装置13と同じ回路である。
