摘要： A multimedia extension unit (MEU) is provided for performing various multimedia-type operations. The MEU may be coupled either through a coprocessor bus or a local CPU bus to a conventional processor. The MEU employs vector registers, a vector ALU, and an operand routing unit (ORU) to perform a maximum number of the multimedia operations within as few instruction cycles as possible. Complex algorithms are readily performed by arranging operands upon the vector ALU in accordance with the desired algorithm flowgraph. The ORU aligns the operands within partitioned slots or sub-slots of the vector registers using vector instructions unique to the MEU. At the output of the ORU, operand pairs from vector source or destination registers may be easily routed and combined at the vector ALU. The vector instructions employ special load/store instructions in combination with numerous operational instructions to carry out concurrent multimedia operations on the aligned operands. In one embodiment, an arithmetic logic unit may be partitioned into at least two logic portions. A first logic portion may be coupled to receive a first operand from a fixed slot of a first register and a second operand from any slot of a second register. A second logic portion may be coupled to receive a third operand from a fixed slot of the first register and a fourth operand from any slot of the second register. The first logic portion may perform an arithmetic operation dissimilar from the second logic portion.

摘要： A system management mode (SMM) of operating a processor includes only a basic set of hardwired hooks or mechanisms in the processor for supporting SMM. Most of SMM functionality, such as the processing actions performed when entering and exiting SMM, is “soft” and freely defined. A system management interrupt (SMI) pin is connected to the processor so that a signal on the SMI pin causes the processor to enter SMM mode. SMM is completely transparent to all other processor operating software. SMM handler code and data is stored in memory that is protected and hidden from normal software access.
