Package mars.mips.dump

Class SegmentWindowDumpFormat

java.lang.Object

mars.mips.dump.AbstractDumpFormat

mars.mips.dump.SegmentWindowDumpFormat

All Implemented Interfaces:

DumpFormat

public class SegmentWindowDumpFormat
extends AbstractDumpFormat

Dump MIPS memory contents in Segment Window format. Each line of text output resembles the Text Segment Window or Data Segment Window depending on which segment is selected for the dump. Written using PrintStream's println() method. Each line of Text Segment Window represents one word of text segment memory. The line includes (1) address, (2) machine code in hex, (3) basic instruction, (4) source line. Each line of Data Segment Window represents 8 words of data segment memory. The line includes address of first word for that line followed by 8 32-bit values.

In either case, addresses and values are displayed in decimal or hexadecimal representation according to the corresponding settings.

Specified by:

dumpMemoryRange in interface DumpFormat

Specified by:

dumpMemoryRange in class AbstractDumpFormat

Parameters:

file - File in which to store MIPS memory contents.

firstAddress - first (lowest) memory address to dump. In bytes but must be on word boundary.

lastAddress - last (highest) memory address to dump. In bytes but must be on word boundary. Will dump the word that starts at this address.

Throws:

AddressErrorException - if firstAddress is invalid or not on a word boundary.

IOException - if error occurs during file output.
