5. How important is sustainable design? How can my organization set up a part/component reuse and recycling program? What are the benefits?

2. ClearSpeed's current CXS700 architecture.

As discussed, mobile devices are evolving quickly and the features supported continue to converge into a single device. The amount of data created and sideloaded by these devices requires ample memory and fast connectivity to the user home PC. USB is the interface used today, but only full-speed USB is supported by most current processors, and it does not deliver sufficient throughput for the amount of data being moved. Internal and external memory is evolving at a rate processors cannot keep up with.

When the perceived difference between the reference and compressed video sequences are small, people prefer the DSCQS method. The human testers are shown a small subset of the video sequence (typically 10 seconds) and they can easily judge small differences in video quality. Long sequences are harder to evaluate as the human testers become fatigued seeing 2 sets of video sequences for each test.

Proximity pairing works by pressing a button on the remote when it is physically close to the device it should control. The remote control sends a broadcast packet, and any device in close proximity will reply to establish a binding. In order to detect which device it is physically close to, the remote control relies on the RF signal strength from the transmitting device when it replies to the broadcast. Calculating the distance between transmitter and receiver from the signal strength at the receiver is based on the attenuation of RF signals over distance. In an RF receiver this signal strength is measured as RSSI (Received Signal Strength Indication). To get an intuitive and user-friendly proximity pairing, the RSSI measurement in the receiver must be accurate.

This background makes it clear that there is a significant problem involved in debugging parallel code, both when initially creating or porting code to a parallel machine and when tuning the performance of the code.

The problem lies in the fact that activity in the solar sector is presently focused on a relatively small number of countries. The UK, for example, has largely turned its back on the technology (look out the window and you may see why) in favour of alternatives such as wind turbines and bio fuels. Consequently, in Europe, the front-runners are Spain (although a recent cap on solar installations by the Spanish government may dampen this) and Germany.

11.3.6 H.263 Coder for Visual Conferencing The H.263 coder from the ITU evolved from their earlier H.261, or px64 coder. As the original name implies, it is targeted at rates that are a multiple of 64 Kbps. To achieve such low bitrates, they resort to a small QCIF frame size, and a variable and low frame rate, with bitrate control based on buffer fullness. If there is a lot of motion in detailed areas that generate a lot of bits, then the buffer fills and the frame rate is reduced, i.e., frames are dropped at the encoder. The user can specify a target frame rate, but often the H.263 coder at, say 64 Kbps, will not achieve a target frame rate of 10 fps. The H.263 coder features a group of blocks (GOB) structure, rather than a GOP, with I blocks being inserted randomly for refresh. While there are no B frames, there is the option for so-called PB frames. The coder has half-pixel accurate motion vectors likeMPEG 2, and can use overlapped motion vectors from neighboring blocks to achieve a smoother motion field and reduced blocking artifacts. Also, there is an advanced prediction mode option and an arithmetic coder option.

Conclusion In situations where the data rate is low, such as a dot matrix LCD, an interface the MCU to the FPGA through the PIO or the EBI is sufficient. However, a high data rate between the FPGA and the MCU, or between some other peripheral and the memories, could monopolize CPU cycles and create bottlenecks on the peripherals. For example, a TFT LCD graphics color will require substantial amount of data to be transferred from the frame buffer to the LCD that would most likely completely overwhelm both the CPU and the EBI. This kind of application will perform better with direct interface from the MCU to the FPGA, while allows the LCD data to be transferred over the DMA, keeping the processor free for processing and the EBI free for other data transfers, such as the main application software running from flash, or in the case of the TFT LCD the usage of SDRAM for single or multiple frame buffers.
