An embedded system includes a microprocessor and performance measuring logic coupled to the microprocessor and configured to record selected performance metrics. In the given routine. In general, a counter is configured to record statistics for each of the performance metrics, and the counters may be controlled using a programmable mask, which is included in a memory coupled to the microprocessor. Based on these metrics, designers may fine-tune software for the embedded system.

Performance measurement for embedded systems

Video information which is organized in a first format is converted to a second format by first scaling the video information to produce scaled video information and then color correcting the scaled video information to produce color corrected video information at a network server. Scaling the video information may be accomplished by first applying a vertical scaling process to the video information to produce vertically scaled video information. Second, an anti-flicker filter may be applied to the vertically scaled video information to produce the scaled video information. The vertical scaling process includes a pixel-by-pixel conversion process wherein, for each group of six scan lines in a frame of the video information, color information for individual pixels which make up the group of six scan lines is scaled to provide color information for pixels in a corresponding group of five scan lines of a frame of the vertically scaled video information. The anti-flicker filter comprises a pixel-by-pixel conversion process wherein for each group of three scan lines in a frame of the vertically scaled video information, color information for individual pixels which make up the three scan lines is scaled to provide color information for pixels in a corresponding scan line of a frame of the scaled video information. Color correcting the scaled video information generally comprises converting R-G-B color information of the scaled video information to Y-U-V color information. The color corrected video information may then be transmitted to a network client via a wireless communication link.
