Specifications

● Data Pattern—Writes four different patterns to memory locations within the specified region. The patterns are 0xFFFF,
0xFF00, 0xF0F0, 0xAAAA, 0xAA55 and 0x5555. The patterns are written as repeated portions of these patterns in
the memory to fill the memory and as Hamming patterns (such as Hamming [8,4], Hamming[16,11], Hamming[32,26] or
Hamming[64,57]) encoding with the additional most significant byte (MSB) parity bit to cover the parity bits in the Hamming
code. This pattern allows for detecting multiple bit errors.
● Data Cache—Performs a rotation of a 16MB array in four clockwise rotations for 16 iterations of the complete rotation.
The 16MB size ensures that memory is not within the cache lines and causes cache ejections through each of the rotations.

The memtool uses long options for the parameters which requires two hyphens in front of the options. Options are required,
optional, or none. If a parameter is required, it is specified as such and must include an equal sign; if an option is optional, it
