Question about Microsoft Windows XP Professional With Servise Pack 2 (e8503040) for PC
Can you be more specific on any details of the error. Here's what SSE2 is: SSE2 extends MMX instructions to operate on XMM registers, allows the programmer to completely avoid the eight 64-bit MMX registers "aliased" on the original IA-32 floating point register stack. This permits mixing integer SIMD and scalar floating point operations without mode switching required between MMX and x87 floating point operations. However, this is overshadowed by the value of being able to perform MMX operations on the wider SSE registers. Other SSE2 extensions include a set of cache-control instructions intended primarily to minimize cache pollution when processing indefinite streams of information, and a sophisticated complement of numeric format conversion instructions. AMD's implementation of SSE2 on the AMD64 (x86-64) platform includes an additional 8 registers, doubling the total number to 16 (XMM0 through XMM15). These additional registers are only visible when running in 64-bit mode. Intel adopted these additional registers as part of their support for x86-64 architecture (officially known as Intel 64) in 2004.
