北京大学ACM比赛题目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime n ...

This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The r ...

书籍  Mobile+Communications+Engineering

By definition, the term “mobile-radio communications” describes any radio communication link between two terminals of which one or both are in motion or halted at unspecified locations and of which one may actually be a fixed terminal such as a base station. This definition applies to both mobile- ...

书籍  Multi-point Cooperative Communication Systems

This book is about multipoint cooperative communication, a key technology to overcome the long-standing problem of limited transmission rate caused by inter- point interference. However, the multipoint cooperative communication is not an isolated technology. Instead, it covers a vast range of resear ...

技术资料  AL422B

The AL422B consists of 3M-bits of DRAM, and is configured as 393,216 words x 8 bit FIFO (first in first out). The interface is very user-friendly since all complicated DRAM operations are already managed by the internal DRAM controller. Current sources of similar memory (field memory) in the market ...
