NOTE: `required' refers to what the specification allows, not what the specific CPU allows. Format is not to be implementation dependent.
n: min number of bits required to be able to represent all parameter types
x: min size required to represent each power of two value less than or equal to the current mode (in bytes, and greater than or equal to 1)
y: min size to specify a particular segment register
Binary format:
type[n], data[<type dependent>]
Types:
Single immediate reference:
Data size: x + [size of immediate value]
data[0 to x-1]:
Size of immediate value
data[x to end]:
Raw value
Shared immediate reference:
Data size: x + [minimum size required to represent an offset in the immediate references section]
data[0 to x-1]:
Size of immediate value
data[x to end]:
Offset into the array of immediate values
Register:
Data size: x + [minimum size required to specify any register]
data[0 to x-1]:
How much of the register to use
data[x to end]:
Which register to use
Memory at single immediate reference:
Uses RAM pointed to by the value as obtained in `single immediate reference` above
SS0 will be used for filling in the segment with unspecified bits
Prepends n bits to the data:
data[0 to n-1]:
Size of memory to use
Memory at shared immediate reference:
Uses RAM pointed to by the value as obtained in `shared immediate reference` above
SS0 will be used for filling in the segment with unspecified bits
Prepends n bits to the data:
data[0 to n-1]:
Size of memory to use
Memory at register:
Uses RAM pointed to by the value as obtained in `register` above
SS0 will be used for filling in the segment with unspecified bits
Prepends n bits to the data:
data[0 to n-1]:
Size of memory to use
Memory at single immediate reference with segment override:
Uses RAM pointed to by the value as obtained in `single immediate reference` above
Prepends n + y bits to the data:
data[0 to n-1]:
Size of memory to use
data[n to n+y-1]:
Which segment register to use
Memory at shared immediate reference with segment override:
Uses RAM pointed to by the value as obtained in `shared immediate reference` above
Prepends n + y bits to the data:
data[0 to n-1]:
Size of memory to use
data[n to n+y-1]:
Which segment register to use
Memory at register with segment override:
Uses RAM pointed to by the value as obtained in `register` above
Prepends n + y bits to the data:
data[0 to n-1]:
Size of memory to use
data[n to n+y-1]:
Which segment register to use
TODO: Will add more later
All memory references go through any configured translation thereof, unless specified otherwise
