main clock meaning in English
母钏
Examples
- The system uses s3c44box processor which is suitable in low cost and dissppation and main clock can reach 130mips , so the system can increase the data processing greatly , matching the data transport demanded from the rfid label to the rfid reader
系统选取适合用于对价位和功耗要求较高的、主频高达130mips的s3c44b0x作为处理器,大大增强了数据的处理速度,适应不断增加的rfid标签和读卡器之间数据传递量。 - 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
本文所阐述的密码芯片在altera公司的apex20kefpga上进行了测试。工作频率达到了40mhz ，占用了3万个le . ，利用altera器件的esb资源，采用内置ram和内置rom设计方法，用一片芯片即可实现整个系统的功能，充分体现了sopc的设计方法和理念，对芯片的仿真和测试均证明芯片功能正确，表明基于可重组体系结构这一重要思想在密码芯片设计中具有特殊的意义。该芯片的设计遵循hdl设计方法学的一般方法。
