- Page 2 NOTES FOR CMOS DEVICES PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred.

Page 15: Board Features
Chapter 2 Board Features As the name implies, the startWARE-GHS-Ravin-E board employs the Ravin-E display controller (µPD72255) as its centrepiece. Also implemented is an SAA7113H or SAF7113H video processor, which is used to digitize a PAL or NTSC standard video signal and optionally overlay it on the graphics. -

Page 17: Functional Description
CRT or TFT displays. Ravin-E can be connected to virtually any 32-bit host CPU with an asynchronous SRAM-like bus interface. A second 32-bit wide data bus connects to standard SDRAMs which serve as the frame buffer for the graphics and the video. Figure 3-1: startWARE-GHS-Ravin-E Block Diagram SAA7113H 8-bit... -
Page 18: Power Consumption
Ravin-E is the second one. 3.1 Power Consumption The startWARE-GHS-Ravin-E board is supplied with a single +5 V DC operating voltage from the main board. The internally required 3.3 V and 2.5 V are generated by linear voltage regulators on the Ravin-E board. -
Page 19: Software Description
We have written a few demo programs, which can be found in the “Software\Ravin-E” directory of the startWARE-GHS-Ravin-E CD. The programs can be compiled for MIPS RISC devices or for V850E devices. Build files for each of these environments are supplied. We have used Green Hills version 3.5.1 for V850 and version 3.6.1 for MIPS. -
Page 20: Display Of Png Files
Chapter 4 Software Description 4.2 Display of PNG Files In order to display png files (Portable Network Graphics), we have ported the free PNG Reference Library libpng (www.libpng.org) to the V850. This library requires the zlib compression library (www.gzip.org), which has also been ported. These two libraries are documented on their respective websites. -
Page 21: Demonstration Programs
Ravin-E's frame buffer instead of the heap. The total size of the frame buffer on the startWARE-GHS-Ravin-E board is 64 MB which is plenty of space outside the current display area. Transfer of the image to the screen location would then be accomplished by a BITBLT command to Ravin-E. -

“os_sleep(20)” delay at the end of function main. 4.4.4 HW-Test HW-Test is a program, which is used by NEC in the startWARE-GHS-Ravin-E production test. It per- forms an initial test of the Ravin-E frame buffer memory, displays some vectors with colour shading on the screen and captures a video via the cinch connectors. -
