Embedded OMAP Processors: OMAP5910 and OMAP5912<br />
Addressing the Needs of Next-<br />
Generation Embedded Designers for<br />
Portable Data Terminal Applications<br />
The dual-core OMAP59xx processor integrates<br />
a TMS320C55x <strong>DSP</strong> core with<br />
an ARM9 core on a single chip for the<br />
optimal combination of application performance<br />
and low power consumption.<br />
This unique architecture offers an attractive<br />
solution to both <strong>DSP</strong> and ARM ®<br />
developers, by providing the low-power,<br />
real-time signal processing capabilities of<br />
a <strong>DSP</strong> coupled with the command and<br />
control functionality of an ARM.<br />
TI’s software development support,<br />
OMAP Technology Centers (OTCs), OMAP<br />
Developer’s Network, and third party<br />
tools provide a user-friendly software<br />
development infrastructure. The<br />
OMAP59xx processors are ideal for<br />
designers working with devices that<br />
require embedded applications processing<br />
in a connected environment such as<br />
portable data terminals.<br />

Familiar Development Environment<br />
Speeds Design Cycle<br />
The OMAP59xx processor enables<br />
embedded developers to program using<br />
familiar development environments by<br />
supporting leading operating systems<br />
such as Microsoft Windows CE, Linux,<br />
Accelerated Technology’s Nucleus,<br />
WindRiver’s VxWorks, Green Hills<br />
INTEGRITY ® , Enea OSE and TI’s <strong>DSP</strong>/BIOS<br />
real-time scalable kernel among others.<br />
This open development environment<br />
makes it possible for designers to deliver<br />
innovative products to the market faster,<br />
utilizing familiar tools, a standard application<br />
programming interface (API) and a<br />
seamless interface to the <strong>DSP</strong> through an<br />
optimized interprocessor communication<br />
mechanism. The built-in interprocessor<br />
communication mechanism eliminates<br />
the need for developers to program the<br />
RISC and <strong>DSP</strong> independently resulting in<br />
reduced programming efforts.<br />
