What is the effect of PCMPEQB MM0,MM1?
What will be an ideal response?
PCMPEQB is packed compare?equal?byte which means that it’s a parallel MMX operation arranged as eight
bytes in a 64?bit MMX register. The comparison is for equality. If both source and destination byte operands are
the same, the value 0xFF is deposited in the corresponding byte of the destination. If the bytes being compared
differ, 0x00 is deposited in the corresponding destination byte. For example, if MM0 = 0x1234567812345678
and MM1 = 0x0000000012FFFF78 the result in MM0 would be 0x00000000FF0000FF. The result of the test (an
all 1s or all 0s byte) can be used as a mask in logical operations.

1. Based on the published specifications that define a usable tool, if any I/O error occurs while reading data, the tool must immediately abort the data capture event. 2. Your new forensic workstation came with two 10K-rpm SAS drives and two 7,400rpm drives. You should install the OS onto the slower drives and save the faster drives for the data sets. 3. The fastest and most durable permanent storage mechanism is the solid state drive. 4. The most commonly seen expansion slot in most current system boards is the PCI-X slot. 5. There is little or no reciprocity between states in regards to the licensing requirements for digital investigators.
