专利汇可以提供Programmable video signal generator with lithographic function专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain plotting and program recording without using a master computer and a recorder by successively setting up command data in a plotting IC simultaneously with writing operation in a recording EEPROM to execute plotting. CONSTITUTION: A key input part 16 inputs a command to be plotted to a central processing unit(CPU), the command is temporarily stored in a random access memory(RAM) 13 as the machine language and the stored contents are written in a specified address of a command buffer by operating the key input part 16. After the end of the writing, the command data are written in an electrically erasable and programmable read-only memory(ROM) 14 by the operation of the key input part 16, and simultaneously with the writing, plotting IC command data are successively written. Then the plotting IC command buffer is released to an operator, so that the operator can directly access the plotting IC. Since a master computer and a recorder are made unnecessary, the system is simplified and the preparation of software for the master computer is made unnecessary.,下面是Programmable video signal generator with lithographic function专利的具体信息内容。
