This interface is defined to factor common data about all OMAP2x3x devices
into a single place; they all have the same internal memory.

Instance Creation |

create(String revision);
// Create an instance-object
ARGUMENTS
revision
a string that identifies revision of the CPU to be
created.
DETAILS
A "data sheet" for a CPU allows one to get specific attributes
for a CPU programatically; e.g., the memory map of the CPU.
Notice that we don't specify CPU registers when we create a
a data-sheet; registers are provided as necessary to the other
functions defined in this interface. This allows one to more easily
get memory maps for several different setting of the registers,
for example.
IOMAP2x3x.getMemoryMap() // instance |
|
Get the memory map that corresponds to the values of the specified
registers
function getMemoryMap(registers);
ARGUMENTS
registers
a hash of named registers to values at the time
an executable is to be loaded (for example)
DETAILS
If a register is not specified and this register can affect the
memory map, the register is assumed to be set to its reset
value (the value of the register immediately after a CPU reset).
RETURNS
Returns an array of
xdc.platform.IPlatform.Memory
objects that represent the memory visible to an
executable running on the CPU.
IOMAP2x3x.getRegisterSet() // instance |
|
The set of valid register names for this CPU
function getRegisterSet();
DETAILS
This function returns the complete set of register names that may be
passed to the
getMemoryMap() function. This function is
only used to enable one to write a "requires contract" for the
getMemoryMap() function.
RETURNS
Returns an array of valid register names (strings) for
this device; only names from this array are valid keys
for the registers argument to
getMemoryMap().
