间歇性404...
被墙坑了无误。。。

Build199预备完成，继续debug……
下一个Build发布。

debug完简化了下代码，算是milestone了……
继续坑。







build 226 rev 1。
loading界面：


加入invalidation后的效果（FPS是伪劣产品，只在有动作进行刷新时有效；上面是invalidated rect四元组(X, Y, Width, Height)）：






显示内嵌点阵的TrueType中文字符会出问题，原因不明。
下面用的是Win7自带宋体simsun.ttc。上面正常的是用FontForge去掉点阵的ttf文件。



对比正常的：



build 273 rev 47
重新部署文本缓冲策略，定长编码大文件随机读取效率即使在模拟器里完爆记事本也绰绰有余（和写字板相当，不过那个显然有预处理过）……
*显示tab暂时懒得搞。


Yet sth is not a Shell

优化逻辑。关键动作40.x/125.0。更改关键动作为ListBox拖动，9.x/27.x。
最后帧复制使用DMA copy， 10.8~11.x/30.x~31.x。
补完ListBox的各种事件 9.9/27.x~29.x。
加入其它功能时FPS不稳定，debug在9.4~9.7/27.x~30.x之间波动。可能是加载器的问题。
优化主消息循环，9.4→9.6。
加入其它内容，再次波动。
b276：
改变本机Color类型从native(ARGB1555)到RGBA8888，9.5~9.6/28.571~29.4→9.5~9.6/30.6~31.250。
但是实机上一直稳定9.09（文件内容/界面略有不同）→ →。。

Surprisingly, almost no efficiency decreased in release configuration.
Hope to see performance on real machine.

SWI 02h (GBA) or SWI 06h (NDS7/NDS9) - Halt
Halts the CPU until an interrupt request occurs. The CPU is switched into low-power mode, all other circuits (video, sound, timers, serial, keypad, system clock) are kept operating.
Halt mode is terminated when any enabled interrupts are requested, that is when (IE AND IF) is not zero, the GBA locks up if that condition doesn't get true. However, the state of CPUs IRQ disable bit in CPSR register, and the IME register are don't care, Halt passes through even if either one has disabled interrupts.
On GBA and NDS7, Halt is implemented by writing to HALTCNT, Port 4000301h. On NDS9, Halt is implemted by writing to System Control Coprocessor (mov p15,0,c7,c0,4,r0 opcode), this opcode hangs if IME=0.
No parameters, no return value.
(GBA/NDS7: all registers unchanged, NDS9: R0 destroyed)
SWI 07h (NDS7) - Sleep
No info, probably similar as GBA SWI 03h (Stop). Sleep is implemented for NDS7 only, not for NDS9, not sure if the functions stops BOTH NDS7 and NDS9?



TCM and DMA and IRQ
No idea if/how IRQs are handled during DMA? Eventually (unlikely) code in TCM is kept executed until DMA finishes (ie. until the IRQ vector can be accessed. Eventually the IRQ vector is instantly accessed (causing to halt the CPU until DMA finishes). In both cases: Assuming that IRQs are enabled, and that the IRQ vector and/or IRQ handler are located outside TCM.


Maxmod init removed, simplified ::main impl @ ARM7.

加了载入文本的默认视图处理反而高了……
果然是cache miss的RPWT么。。
