J T AG 接口插座與DSP芯片的距離:為了保證JTAG信號不受干擾,需
要注意兩者之間的距離不超過六英寸(15甲24厘米),超過這個距離,就需要在中
間加緩沖芯片。本設(shè)計中使用了244作為緩沖芯片,但其原因不是由于器件之間
距離過長,而是考慮到仿真器工作在5V電壓,DSP引腳為3.3V,為了電平兼容
性而進行的電壓轉(zhuǎn)換功能。
T-kernel 的extension源代碼,是日本最著名的T-kernel所獨有的,適合開發(fā)T-kernel的朋友們使用!
TK/SE is the program that extends T-Kernel and provides the functions such as a file system and a process management.
The TK/SE archive to be provided is comprised of the main portion and the 2 extended file system portions, and TK/SE object is built by adding these to T-Kernel source.
a) tkernel_se_1.00.00.tar.gz Main source of T-Kernel/SE
b) extfs_fatfs_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (FAT)
c) extfs_cdrom_1.00.00.tar.gz Difference source of T-Kernel/SE extended file system (CD-ROM)
