Introduction Digital signal processing (DSP) occurs in communications, audio, and multimedia devices, imaging and medical equipment, smart antennas, automotive electronics, MP3 players, radar and sonar, and barcode readers, to name but a few. According to market research firm Forward Concepts' November 1, 2005 DSP/Wireless Market Bulletin, the estimated market for programmable DSP chips should exceed $8B in 2005.

Since most of the sound data is synthetic (instructions to the SA Orchestra similar to MIDI files), SA file size and the compression ratios approach 100:1. Since the song is re-mixed by the playback device, the device could also choose an optimal mix for the listening environment, such as 5.1 Dolby Digital or DTS for home, a headphone mix for private listening or a 4-channel mix for automobiles.

New Dolby coders, Digital Plus and MLP Lossless provide increased capabilities which will be applied to the consumer audio, automotive, PC, and gaming markets.

Dolby Digital Plus, with its very efficient (< 320kbps for 5.1 channel audio) broadcast bit rates, can carry more than 8 multi-channel audio program channels. It also supports multiple languages in a single encoded bit-stream that will playback on existing Dolby systems.

Dolby MLP Lossless is the core technology multi-channel and stereo DVD-Audio. MLP Lossless encodes up to six channels of 96 kHz/24-bit audio, or two channels of 192 kHz/24-bit audio onto a DVD-audio disc with playback identical to the studio master.

Digital Content Caching and Networking Technology Cached or stored digital content (such as personal video recorders and MP3 players) will allow you to make your own commercial-free radio station” by placing favorite songs on your MP3 player.

Networks will be increasingly used to transfer digital content to users on demand and will deliver streaming digital audio/video with performance equal to current broadcast media.

IP packet prioritization will help eliminate annoying program interruptions. Data packets can be forwarded to many different computers to reduce the amount of network traffic per stream and accommodate more users.

Improved digital content encoding algorithms, along with new usage models of the network, will give consumers new content delivery alternatives to broadcast and CD/DVD rentals. The popularity of legitimate digital music downloading services will also be repeated for TV programs, audio books, documentaries, and movies at affordable prices-per-download. Home entertainment networks and whole-house audio and video systems will be the next step beyond the home theater.

Mesh networks are like a fish net spread over an area, with each knot representing a WiFi node that passes data to and from the central connection. Mesh networks are ideal for small towns, rural communities, industrial and educational campuses, or for workgroups. Mesh networks are robust, allowing packets of data to take several paths around hills, buildings or dense foliage.

This handset is interesting due to the memory components Nokia chose (Fig. 1) . It's not unusual for Nokia to employ Samsung memory. For instance, in the Nokia 6630, separate Samsung NOR and NAND/DRAM components are employed.

While this is the first time that we've seen Samsung's OneNAND in a commercially available product, Samsung informed us that OneNAND now ships in more than 120 handset designs. By combining the NOR, NAND, and mobile SDRAM in a single component, Nokia is able to realize a more cost effective solution (Fig. 2) .

A key feature of Samsung's OneNAND is in the approach taken to store and execute data. The concept takes advantage of both high-speed data read functions, normally associated with NOR flash, and the large storage capabilities associated with NAND flash. For example, the device has a read bandwidth of 108 Mbytes/s, comparable to NOR, while at the same time is offered in densities up to 2 Gbits, reaching the sweet spot” in mobile devices. In addition, the OneNAND has a write memory speed approaching 9.3 Mbytes/s, exceeding both the NOR and NAND counterparts.
