Changelog:

1. A newly created build-in dynamic compiler which can increase the runtime
preformance dramatically.
2. Users can input commands from the emulated serial console.

===========================================================
* Version 0.4.0:
o You can type commands in the emulated serial console.
o Add UTF-8 traditional chinese translation.

* Version 0.3.0:
o Add a dynamic compiler.

* Version 0.2.0:
o Add threaded code optimization technology.

* Version 0.1.0:
o The original version. Pure interpreter.

ARMware is an emulator for ARM micro-processor. It can only emulate
Intel StrongARM SA-1110 as core for now. However ARMware emulates
not only the Intel StrongARM cpu, but also Compaq iPaq H3600.

The hardware components that ARMware can emulate are:

1. ARM architecture version 4 core
2. ARM standard system coprocessor (CP15)
3. Memory Management Unit (MMU)
4. Translation Lookaside Buffer (TLB)
5. LCD Controller
6. DMA Controller
7. EGPIO
8. Operation System Timer
9. Reset Controller
10. Real Time Clock (RTC)
11. GPIO Controll Block
12. Interrupt Controller
13. Power Management
14. Serial Port 1
15. Serial Port 3
16. Intel StrataFlash J3 Flash ROM
17. Atmel micro-controller
18. LCD screen
19. Touch panel

The advantages of ARMware are:

1. The build-in threaded code engine will cache a block of ARM machine
codes, so that it can increase the execuating speed.

2. The build-in dynamic compiler will translate a block of ARM machine
codes to a block of x86 machine codes, so that it can increase the
runtime preformance dramatically.

3. In addition, I use assembly codes to re-write parts of it to increase the
run-time performance. For example, I use MMX and SSE2
instructions to rotate an angle of 270 degrees of the LCD screen
(That is to say, you have to execute ARMware in a CPU with SSE2
instruction sets, like Pentium M or Pentium 4). In addition,
I also use assembly codes to accomplish the condition codes setting
of ARM.

4. ARMware has a build-in memory management subsystem to serve all
memory allocation and deallocation. Through heavely testings,
ARMware almost doesn't have any memory leaks.

5. It can use Qt (Screenshots) or Gtk (Screenshots) as its user interface.
However, because of the liscense of Qt, I could only release the
version of ARMware using Gtk as its interface.

6. ARMware has a serial console window (Movie), so that users can see
the serial console outputs from ARMware, and input any commands
into it.

7. It can use GNU dbm (Screenshots) or xml (Screenshots) as its machine
database. However, because of the license of GNU dbm, I could only
release the version of ARMware using xml as its machine database.

8. Conform to the i18n, and ARMware includes two traditional chinese
translations for the Big5 and UTF-8 locales.

9. Contains a full functional utility to burn a new Flash ROM
(Screenshots),
which can be used to emulate the burning operations in the real world,
and you can use the new created flash rom to start ARMware.

10. Every user's machine database is placed under their home directory.
Thus different users can have different machine database.
