Method Summary
`void`	`clearProfile()` This method clears the profile table.
`byte[]`	`get()` This method returns the byte array used to represent the memory.
`int`	`getBaseAddress()` This method returns the current base address of the memory.
`boolean`	`getEndian()` This method returns the endian (byte order) of the memory.
`int`	`getMaxProfile()` This method returns the largest value currently in the profile table.
`protected int`	`getOffset(int addr)` This method takes an address and converts it into and offset into the array used to represent the memory.
`int[]`	`getProfile()` This method returns the current memory access profile data as an array of integers.
`int`	`getProfile(int addr)` This method returns the number of times an address has been visited by the Program Counter.
`int`	`getProfileGranularity()` This method returns the profile granularity.
`boolean`	`isReadable(int addr)` This method returns true if the current address is readable and false otherwise.
`boolean`	`isValidAddress(int addr)` This method returns true if the address is valid and false otherwise.
`boolean`	`isWriteable(int addr)` This method returns true if the current address is writeable and false otherwise.
`void`	`profile(int addr)` This method increments the profile count for a particular address.
`byte`	`read(int addr)` This method returns a byte from the memory at address 'addr'.
`short`	`read16(int addr)` This method returns a 16-bit short from the memory at address 'addr'.
`int`	`read24(int addr)` This method returns a 24-bit unsigned integer from the memory at address 'addr'.
`int`	`read32(int addr)` This method returns a 32-bit int from the memory at address 'addr'.
`long`	`read64(int addr)` This method returns a 64-bit long from the memory at address 'addr'.
`void`	`resize(int size)` This method resizes the memory array.
`void`	`setBaseAddress(int baseAddr)` This method sets the base address of the memory.
`void`	`setEndian(boolean endian)` This method sets the endian (byte order) of the memory.
`int`	`size()` This method returns the size of the memory.
`void`	`write(int addr, byte data)` This method copies a byte from 'a' into the memory at address 'addr'.
`void`	`write16(int addr, short a)` This method writes the 16-bit value 'a' to the requested memory address.
`void`	`write24(int addr, int a)` This method writes a 24-bit value 'a' to the requested memory address.
`void`	`write32(int addr, int a)` This method writes the 32-bit value 'a' to the requested memory address.
`void`	`write64(int addr, long a)` This method writes the 64-bit value 'a' to the requested memory address.
