Double-congruence, double-homomorphism and double-isomorphism in a unary algebra;

一元泛代数的双同余、双同态与双同构

The representative application of the two-frame CTM is introduced predominantly, of which the implementation in circuit and the result are given with the Double Data Rate Synchronous Dynamic RAM(DDR SDRAM)served as the main memory.

重点介绍了两页式转置存储器结构的典型应用,给出了以双数据率同步动态内存(DDRSDRAM)作为主存储器构成的两页式转置存储器的电路结构和实现结果。
