The VPOM-2420 is a proven example of the capabilities delivered by the Synopsys virtual prototype portfolio of system-level tools, models and services. It has been developed and deployed using the Innovator virtual prototype creation and runtime tool as well as models from the DesignWare System-Level Library. In addition, customer-specific models have been added. With this fast, full-function software simulation capability, software developers were able to start development and integration of their software before the hardware was available.
This virtual prototype is a high performance software simulator of the TI OMAP2420 Software Development Platform (SDP2420) designed for advanced mobile phone video and imaging development. OMAP2420 is based on the OMAP2 architecture that includes the ARM11 and C55xx DSP. The VPOM-2420 powers dramatic gains in developer productivity by integrating with the software developer’s preferred development environment for application, middleware, operating system and driver development, making it a feasible alternative even after silicon development boards have become available.
The OMAP2420 graphics subsystem incorporates the next-generation imaging, and video and audio accelerator standard, enabling system designers to have access to a full simulation of the accelerator.
The VPOM-2420 models most of the components and peripherals of the OMAP2420 as well as the user interface including touch-screen, stylus and terminals. This prototype also includes the development boards that contain the audio codec and touch-screen controller (TSC21001), camera interface (OV9640), various flash memory models and more.
The simulation of the TI TWL92230 and TWL4030 Power Management ICs allows software developers the ability to fully understand the interaction of their software with hardware power management on the OMAP platform as well as on the chip power management hardware. The prototype allows both control of the power management hardware and insight into the interaction of the hardware with the independent power-management services of the operating system. Developers can visualize the applied system voltage scaling over time through advanced time graphs and can verify that desired power states have been invoked or implemented correctly by detailed logging of all power events through power dashboards and frequency dashboards.
Advanced Multi-core Debugging
The VPOM-2420 virtual prototype enables greater debug visibility and efficiency by providing heterogeneous and homogeneous multi-core debugger support, including Texas Instruments Code Composer Studio™.
Debugging multi-core SoCs with virtual prototypes is more efficient than with JTAG and physical hardware because JTAG scan chains only stop one processor at a time. Stopping only one processor at a time makes it nearly impossible for the developer to understand the exact system state with the other processors, which continue running. In the VPOM-2420, the entire set of on-chip cores, including the ARM and DSP cores, stop when either a software or hardware breakpoint is reached. This allows unmatched debug visibility into the complete system, thereby improving developer productivity.
