Operator Encoding Macro
GT – Returns TRUE if P[i] > MatchObject 5 MGT
Example
Following are some example uses of Match:
Name (P1,
Package () {1981, 1983, 1985, 1987, 1989, 1990, 1991, 1993, 1995, 1997, 1999, 2001}
)
// match 1993 == P1[i]
Match (P1, MEQ, 1993, MTR, 0, 0) // -> 7, since P1[7] == 1993
// match 1984 == P1[i]
Match (P1, MEQ, 1984, MTR, 0, 0) // -> ONES (not found)
// match P1[i] > 1984 and P1[i] 2, since P1[2]>1984 and P1[2] 1984 and P1[i] 3, first match at or past Start
19.5.78 Memory24 (Memory Resource Descriptor Macro)
Syntax
Memory24 (ReadAndWrite, AddressMinimum, AddressMaximum, AddressAlignment,
RangeLength, DescriptorName)
Arguments
ReadAndWrite specifies whether or not the memory region is read-only (ReadOnly) or read/write
(ReadWrite). If nothing is specified, then ReadWrite is assumed. The 1-bit field
DescriptorName._RW is automatically created to refer to this portion of the resource descriptor,
where ‘1’ is ReadWrite and ‘0’ is ReadOnly.
AddressMinimum evaluates to a 16-bit integer that specifies bits [8:23] of the lowest possible base
address of the memory range. All other bits are assumed to be zero. The value must be an even
multiple of AddressAlignment. The 16-bit field DescriptorName._MIN is automatically created to
refer to this portion of the resource descriptor.
AddressMaximum evaluates to a 16-bit integer that specifies bits [8:23] of the highest possible base
address of the memory range. All other bits are assumed to be zero. The value must be an even
multiple of AddressAlignment. The 16-bit field DescriptorName._MAX is automatically created to
refer to this portion of the resource descriptor.
AddressAlignment evaluates to a 16-bit integer that specifies bits [0:15] of the required alignment for
the memory range. All other bits are assumed to be zero. The address selected must be an even
multiple of this value. The 16-bit field DescriptorName. _ALN is automatically created to refer to
this portion of the resource descriptor.
