VHDL源碼其中“music_rom”使用FPGA廠商提供的工具生成的,如Altera的Quartus II 及其宏功能生成的這些文件。 另外,我們還希望實(shí)現(xiàn)以下功能: * 播放音樂(lè)時(shí),在ROM的結(jié)尾處暫停 * "fullnote"值為0時(shí),表示靜音 所以我們將原來(lái)的程序的最后一行從

T-kernel 的extension源代碼,是日本最著名的T-kernel所獨(dú)有的,適合開(kāi)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)
