基于ATtiny12的专用存储芯片的设计与实现

ASIC芯片全定制费用高、风险大、周期长，因此在全定制之前一般先用FPGA或CPLD等可编程逻辑器件做功能验证。但在一些空间极为有限、成本极低的应用场合，采用FPGA或者CPLD显然不是最佳的解决方案。而利用体积小、性能强、成本低的单片机实现芯片全定制将是一个不错的选择。按此设想，文章给出了一种基于微处理器的科学、经济、快速的ASIC芯片功能验证方案，并成功设计出用于某通信设备中的专用加密芯片。

The Design and Realizing of the Special Memory Chip Based on ATtiny12

ASIC chip full-custom is high expenditure ,high risk and long period, As a result,we generally verify the chip before full-custom with progamable logic devices such as FPGA,CPLD and so on.But in some space-limited,low-spend application, using FPGA or CPLD is not the best way.On the contrary,using microcontroller is a reasonable choice,that is mini-size,power-feature and low-spend.So this paper introduces a scientific,economic and fast method for ASIC chip verification based on microprocessor.and successfully design a special encryption chip using in a communication device.
