Calculator chip adopted as data path of single bus, and ALU of 4bit was the base of operation, inner RCOSC produced stable clock source, SRAM adopted as memory, and microcontroller adopted as ROM architecture.

• 计算器芯片硬件系统采用单总线数据通路结构，以4位ALU为运算基础。 内部RC振荡经流片验证可产生十分稳定的时钟源，数据存储区采用SRAM结构实现，存储单元为6管CMOS静态存储单元，微控制器则采用与-或结构ROM实现。
