  • MAX7060的ASK_FSK的ISM射频发射机

    Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry ca ...

  • This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel.

    This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate i ...

  • This version of the code is compatible only with the AT89C2051 due to the location of the data buf

    This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051.

  • 这是一个不到2000行的操作系统

    这是一个不到2000行的操作系统,巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间,每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1),但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样,设置MVA对应的页表指向不同物理地址就可以很方便地让各进程 ...
