codec芯片TLV320AIC23介绍

mmuos
- 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运行空间相互隔开。代码很少,注释丰富,希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。 -This is a

jtag_cpld_vhdl
- JTAG CPLD实现源代码,比用简单并口调试器快5倍以上。 以前总觉得简单的并口jtag板速度太慢,特别是调试bootloader的时候,简直难以忍受。最近没什么事情,于是补习了几天vhdl,用cpld实现了一个快速的jtag转换板。cpld用epm7128stc100-15,晶振20兆,tck频率5兆。用sjf2410作测试,以前写50k的文件用时5分钟,现在则是50秒左右。tck的频率还可以加倍,但是不太稳定,而且速度的瓶颈已经不在tck这里,而在通讯上面了。 -JTAG CPLD
