Constructor Details

AddByteMappedMemoryBlockCmd

public AddByteMappedMemoryBlockCmd(String name,
 String comment,
 String source,
 Address start,
 long length,
 boolean read,
 boolean write,
 boolean execute,
 boolean isVolatile,
 Address mappedAddress,
 ByteMappingScheme byteMappingScheme,
 boolean isOverlay)

Create a new AddByteMappedMemoryBlockCmd with a specified byte mapping scheme. Byte mapping scheme is specified by two values schemeDestByteCount and schemeSrcByteCount which may be viewed as a ratio of number of destination bytes to number of mapped source bytes. When the destination consumes bytes from the mapped source it consume schemeDestByteCount bytes then skips (schemeSrcByteCount - schemeDestByteCount) bytes before repeating the mapping sequence over the extent of the destination block. The block start address and source mappedAddress must be chosen carefully as they relate to the mapping scheme when it is anything other than 1:1.

Parameters:

name - the name for the new memory block.

comment - the comment for the block

source - indicates what is creating the block

start - the start address for the the block

length - the length of the new block

read - sets the block's read permission flag

write - sets the block's write permission flag

execute - sets the block's execute permission flag

isVolatile - sets the block's volatile flag

mappedAddress - the address in memory that will serve as the bytes source for the block

byteMappingScheme - byte mapping scheme (may be null for 1:1 mapping)

isOverlay - if true, the block will be created in a new overlay address space.

AddByteMappedMemoryBlockCmd

public AddByteMappedMemoryBlockCmd(String name,
 String comment,
 String source,
 Address start,
 long length,
 boolean read,
 boolean write,
 boolean execute,

Create a new AddByteMappedMemoryBlockCmd with 1:1 byte mapping scheme

Parameters:

name - the name for the new memory block.

comment - the comment for the block

source - indicates what is creating the block

start - the start address for the the block

length - the length of the new block

read - sets the block's read permission flag

write - sets the block's write permission flag

execute - sets the block's execute permission flag

isVolatile - sets the block's volatile flag

mappedAddress - the address in memory that will serve as the bytes source for the block

isOverlay - if true, the block will be created in a new overlay address space.
