SSE does not have such a restriction. The arrangement of the registers in MMX and SSE is illustrated in Figure 2. Applications related to 3D graphics, in particular, should see a substantial benefit. In fact, SSE was created specifically for 3D. Games and other applications that use a 3D back-end to display 2D or 2.5D, as well as applications that use vector graphics at the back end, also stand to benefit. The Case of 3D 3D graphics typically consists of manipulating large sets of floating-point numbers used to specify the position of a point in 3D space.
Manipulation involves performing floating-point calculations on the data set.
With the help of SSE instructions, the application will be able to process more data per instruction. The resulting speed increase translates into a better experience for the user. Application developers can also add more data or more complex calculations to create better effects and generate a richer experience for the user. Streaming SIMD Extensions SSE adds 70 new instructions to the processor. SSE requires support from the operating system, which can save and restore the processor state as required.
