programmable rom 中文意思是什麼
-
Eeprom electrically erasable programmable rom
電擦寫可編程只讀存儲器 -
Cryptogrammic chip introduced in this paper has been tested on the altera ' s apex20ke fpga. the main clock frequency reached 40mhz. the chip includes 30, 000 les. in order to utilize esb resource in altera ' s chip, we adopted embedded rom and ram and can realize the function of whole system with only one chip. lt is the embodiment of methodology and notion of sopc ( system on a programmable chip ). the simulation of this cryptogrammic chip proves the correctness of function of the chip, which shows that the important ideology based reconfigurable architecture has special significance in designing of cryptogrammic chip
本文所闡述的密碼晶元在altera公司的apex20kefpga上進行了測試。工作頻率達到了40mhz ，佔用了3萬個le . ，利用altera器件的esb資源，採用內置ram和內置rom設計方法，用一片晶元即可實現整個系統的功能，充分體現了sopc的設計方法和理念，對晶元的模擬和測試均證明晶元功能正確，表明基於可重組體系結構這一重要思想在密碼晶元設計中具有特殊的意義。該晶元的設計遵循hdl設計方法學的一般方法。 -
This master degree thesis, based on the observing of developing actuality of on - site electrical apparatus monitoring technology, aims at overcoming the problems existing in former on - site monitoring system, such as unable to realize multiple channels sampling and hold, unable to carry out multiple channel programmable magnification, unable to monitor frequency, low pick up bits, external rom low speed data saving, inefficient data query method, inflexible debugging and installation, low precision etc. by introducing eda ( electrical design automation ) technology, we put forward a creative circuit design scheme, which can considerable updated the on - site monitor system
本文根據電氣設備絕緣在線監測技術的發展現狀，針對以往在線監測數據採集系統存在的集成度低，不能實現多通路并行采樣，不能實現多通道同時程式控制放大，不能進行同步頻率監測，采樣位數較低，採用外部存儲器方式，對數據進行查詢的訪問方式，安裝調試不靈活等缺點，提出了應用現代微電子技術電子設計自動化（ eda ）技術實現對在線監測數據採集系統的改進。 -
Electrically erasable, programmable read - only memory. ( pronounced " double - e " - prom. ) a type of rom that can be erased electronically
電可擦的，可編程的只讀存儲器。一種rom能被電擦除。
