LKT4101 防抄板专用协处理器芯片采用专用的智能卡芯片平台，内置凌科芯安公司自主开发的嵌入式系统，专门为保护用户代码，防止非法访问和外部攻击而设计的新一代安全芯片。处理器使用8051内核，采用串口通讯协议，用户可以把主要算法放到芯片内部，编程语言基于标准C，开发简单方便，同时，内部大容量的数据空间可作为用户扩展数据存储器，存放重要特征数据。-LKT4101 anti-copy board dedicated coprocessor chip dedicated smart card chip

In this paper, a fast and memory efficient version of set partitioned embedded block (SPECK) image coder is proposed. Due to use of linked lists, SPECK algorithm, requires large run-time memory, making it unsuitable for memory constrained portable mu
