EHW can be implemented combining learning networks such as Neural Networks (NNs) and programmable devices such as FPGA (Field Programmable Gate Array). As such research of EHW, Block-Based Neural Networks (BBNNs) have been proposed. BBNNs have simplified network structures and have been attracting attention with their ease of hardware implementation. In particular, Block-Based Pulsed Neural Networks (BBPNNs) which adopt a pulsed neuron model instead of an analogue neuron model in BBNNs have been proposed in order to solve the problem that BBNNs use many multiplier circuits and require large scale hardware resources for implementation. In addition, applying Back Propagation (BP) which is common learning algorithm of NNs to BBPNNs has been proposed. In this paper, we propose two approximation methods in order to reduce hardware resources which are necessary to apply BP to BBPNNs. In the proposed methods, we approximate input values and derivative values of activation function in BP. Results of computational experiments indicate the validity of the proposed methods.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌: \u003c\/strong\u003e\u003ca href=\"\/products\/ieej-rc13608\"\u003e電気学会論文誌C（電子・情報・システム部門誌） Vol.136 No.8 （2016） 特集Ⅰ：知能メカトロニクス分野と連携する知覚情報技術　特集Ⅱ：国際会議ICESS 2015\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ: \u003c\/strong\u003e1230-1236 p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e論文／日本語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e電子版へのリンク: \u003c\/strong\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/136\/8\/136_1230\/_article\/-char\/ja\/\"\u003ehttps:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/136\/8\/136_1230\/_article\/-char\/ja\/\u003c\/a\u003e\u003c\/p\u003e","brand":"IEEJ-P10","offers":[{"title":"冊子印刷（一般価格770円\/会員価格550円） \/ A4 \/ 7","offer_id":46349953302767,"sku":"IEEJ-RC13608-027-PRT","price":770.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-RC13608_1586adb6-e968-47c9-8736-aec0b4f6a45c.png?v=1743166097","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-rc13608-027","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
