Nvidia announced that its PhysX technology is now available to Wii developers. This follows a similar announcement Wednesday, when Nvidia said it has become a PhysX tools and middleware provider for Sony's PlayStation 3.

As a result, Nvidia's PhysX technology software development kit (SDK) is now available to registered Wii developers, the graphics chip supplier said.
Nvidia's PhysX technology, based on the laws of physics, enables game objects to respond dynamically to physical events in a game. Typically, Nvidia trumpets the performance of PhysX on its graphics chips. But this applies only to PCs, according to Nvidia spokesman Bryan Del Rizzo. In the case of game consoles, the PhysX processing is done by the CPU, not the GPU--even if a GPU is present. (CPU stands for central processing unit. GPU for graphics processing unit.)
"Based on all the processing cores in the GPU, we can do a lot more processing on the GPU than the CPU. That doesn't mean the CPU isn't a great place to do processing, but we can just take more advantage of an Nvidia GPU," Del Rizzo said.
The Nintendo Wii uses an PowerPC-based "Broadway" CPU and an AMD-ATI "Hollywood" GPU. The Sony PlayStation 3 uses an IBM Cell processor and an Nvidia GPU.
"Adding a PhysX SDK for Wii is key to our cross-platform strategy and integral to the business model for our licensed game developers and publishers," Tony Tamasi, senior vice president of content and technology at Nvidia, said in a statement. The Nvidia PhysX SDK consists of a full-featured application programming interface (API) and physics engine.
Taiwan Semiconductor Manufacturing, the largest contract chip manufacturer in the world, will crank up its MEMS foundry business. Micro-Electro Mechanical Systems (MEMS) technology is used in Apple's iPhone and the Nintendo Wii.

In the iPhone, a device called an accelerometer detects when the user rotates the iPhone from portrait to landscape modes, then automatically adjusts the display, so the entire width of a web page or a photo can be seen in its proper aspect ratio.
Hewlett-Packard also uses MEMS technology for its inkjet print-head that combines integrated electronics with microfluidic channels to control ink droplets when printing.
TSMC will provide manufacturing services such as surface micromachining and manufacturing processes for CMOS-MEMS integration and packaging, according to Nikkei's Tech-On. (CMOS stands for complementary metal oxide semiconductor, a common class of integrated circuits used in microprocessors.)
MEMS technology, which in the past was limited mainly to in-house manufacturing or automotive products, is now being applied to a raft of consumer devices and mobile phones, the Tech-On report said.
The MEMS industry was estimated to be worth US$5.95 billion in 2007 and it is expected to exceed US$10.771 billion in 2011, the report said.
TSMC will detail the company's MEMS business plan at a technical seminar in Tokyo on May 15, the report said.
