RTTarget Features
- Target Booting
RTTarget-32's boot code can boot applications directly from
floppy disk, hard disk, EPROM disk, flash disk, ROM, a BIOS
extension, or DOS. At power-on or reset, the boot code
initialises the target computer's hardware, sets up system
data structures such as the GDT, IDT, and the page table,
and starts the application. A PC compatible BIOS can be used
for booting, but is optional. RTTarget-32's boot code can
control the complete boot sequence starting at the boot
vector.
- Cross Debugging Over Serial Ports, Parallel
Ports, and Ethernet
Source-level debugging is supported using Borland's free
Turbo Debugger or the debugger integrated in Microsoft
Visual Studio 6.0/.NET/2005/2008/Express. Host and target
computers are connected using a serial link at up to 921600
baud, a parallel port, or over Ethernet. With RTIP-32, the
application can use the same Ethernet interface as the cross
debugger if only one Ethernet interface is available.
- Run-Time Library
RTTarget-32 includes functions for physical memory access,
port I/O, hardware interrupt handling, serial I/O, real-time
clock access, PCI and PnP BIOS calls, PCMCIA card
management, 387 FPU emulation, and more.
- Win32 Emulation Library
RTTarget-32 provides about 270 Win32 API functions, allowing
it to run many Win32 programs unmodified. The Win32 API
emulation covers memory management, file I/O (RAM files,
console files, printer ports), console I/O (screen and
keyboard), time-of-day and system tick, DLL management
(LoadLibrary/GetProcAddress), exception handling, access to
Win32 resources, memory mapped files, etc.
- Supports C/C++ and Pascal Run-Time Systems
The compiler's run-time system functions such as printf,
malloc, fopen, etc., are fully supported. Even advanced C++
and Pascal features such as exception handling, run-time
type identification, etc., are available. Alternatively,
programs can run without run-time system for even less
memory overhead.
- Low Resource Requirements
32-bit programs developed with RTTarget-32 can run in as
little as 16k of memory. A typical "Hello World" program
with RTTarget-32's Win32 emulation library, keyboard and
screen driver, and a full C++ run-time system can boot and
run on a system with about 64k of total memory.
- Supports Privilege Levels
Programs can run at CPU privilege level 0 or 3 to optimise
either for maximum protection or best performance.
- Supports Page-Level Protection
The CPU's memory protection features are used to guarantee
that programs cannot overwrite protected data, code, or
critical system tables.
- 387 FPU Software Emulator
Even on CPUs without a hardware floating point unit,
applications can use floating point calculations and types
such as float, double, and long double. The 387 math
emulator is fully reentrant and interruptible.
- Multiprocessor Support
RTTarget-32 has functions to start and stop additional CPUs.
Spinlocks and inter-processor interrupts are available to
synchronise execution among CPUs. While RTTarget-32 does not
contain a multitasking scheduler,
RTKernel-32
can use the multiprocessor support to schedule threads on up
to 32 CPUs.
- APIC Support
If the target has at least one IOAPIC (Input Output Advanced
Interrupt Controller), RTTarget-32 applications can use it
to replace the legacy i8259 interrupt controllers. APIC mode
supports a higher interrupt load and up to 32 (instead of
15) interrupt signals, requiring less IRQ sharing.
- Supports DLLs
Applications consist of one main program (the .exe file) and
up to 31 DLLs, which can be statically linked into a program
image or loaded dynamically through a file system.
- Data Compression
Program code and data can be compressed to save EPROM or
boot disk space and accelerate downloads.
- RAM Files
Even when
RTFiles-32 is not used, file I/O can be simulated with
file images located in reserved RAM or ROM on the target.
With On Time's embedded file system RTFiles-32, files on
disk can also be accessed.
- Drivers
RTTarget-32 has built in drivers for keyboard, text-mode
screen, serial ports, parallel ports, PS/2 and serial mice,
and PCMCIA controllers. Since RTTarget-32 allows direct
access to physical memory, I/O ports, and hardware
interrupts, developing additional drivers is very easy.
- Supports Platform RTOS32Win from acontis
technologies
With the add-on component RTVmf-32, On Time RTOS-32 programs
can be executed under
RTOS32Win from acontis
technologies. RTOS32Win is a virtual machine framework
which can execute On Time RTOS-32 programs parallel to
Window under real-time conditions.
- Supports the Real-Time Hypervisor from Real-Time
Systems
With the new add-on component RTRth-32, On Time RTOS-32
programs can be executed under the
Real-Time Hypervisor from
Real-Time
Systems. The Real-Time Hypervisor can execute several
operating systems or several instances of the same system on
separate cores of multi-core or multi-CPU systems.
Using RTTarget-32
RTTarget-32 programs are compiled as standard console mode programs for 32-bit Windows; the RTTarget-32 library Rtt32.lib is simply linked to the application. The resulting .exe file is converted by RTTarget-32's locator to produce a binary image of the application. This binary image can be programmed into an EPROM, written to a boot disk, or submitted to the debugger for downloading. For example, the commands:
cl Test.cpp Rtt32.lib
Rtloc Test
Bootdisk Test A:
would compile, link, and locate program Test and place it on an RTTarget-32 boot disk as a self-booting application. RTTarget-32 is shipped with many example projects that show how to use the RTTarget-32 locator and other tools with Microsoft Visual Studio and other compilers.
