Microsoft Word - Lab2.docx Lab #2 CoSc 20203 Fall 2021 ARM Machine Instructions Due: Thursday Sept 30 Midnight DESCRIPTION From Wikipedia: “ARM, previously Advanced RISC Machine, originally Acorn RISC Machine, is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments. Processors that have a RISC architecture typically require fewer transistors than those with a complex instruction set computing (CISC) architecture (such as the x86 processors found in most personal computers), which improves cost, power consumption, and heat dissipation. These characteristics are desirable for light, portable, battery-powered devices—including smartphones, laptops and tablet computers, and other embedded systems.” We will deal with a very small set of the arm instruction set, basically we interested in generating the instruction hardware code for data processing instructions such as: ADD r0,r1,r2; add r1 to r2 and put the result in r0 That instruction tells the CPU to add a “word” (32-bit) value from data register 0 to the value in data register1 and put the results in r2. In machine language, the instruction looks like E0810002 in Hexadecimal or in Binary For this we need to understand the instruction hardware format for the 32 bit ARM7 which is as follows For the instructions that we will implement the condition, I, S, Shift (size and op) and ST bits are predefined as follows: The codes of the instructions that we will be only the following ones: Sources: http://vision.gel.ulaval.ca/~jflalonde/cours/1001/h17/docs/arm- instructionset.pdf https://en.wikipedia.org/wiki/ARM_architecture Images of ARM chip based devices may be located at https://duckduckgo.com/?q=ARM+chip+based+devices+&t=h_&iax=images&ia=images ASSIGNMENT Write a Java application with a graphical user interface that allows a user to encode and decode the sixteen ARM7 instructions described above for sixteen registers. The program must provide the following functionalities • Conversions should be done from Assembler Mnemonics to Assembler Code and vice versa. • Upper and lowercase are accepted and represent the same instruction • Generate the message of errors if the input cannot be translated (i.e. encoded/decoded) • Display JTextFields with the instructions encoded in both binary and hexadecimal during session should be provided • Exception handling for checked and unchecked exceptions must be provided The design of the interface is left to you. A Zip file with this requirements (i.e. screenshots, manual, jar, javadoc, src) should be submitted using D2L. You should use appropriate widgets to allow the user to enter a four digit hex number and request that it be decoded into assembly language or enter an assembly(in binary) language instruction and request that it be encoded into hex representation. Your program needs to encode/decode only the sixteen instructions shown above. Here is an initial visual guide on the final product. Note that your task is only the software translation (i.e. encoding/decoding) and not the hardware execution of the instructions. This is a string processing application, so in order to complete this project you must use the StringTokenizer class, substrings and testing characters in a String as we have seem in in class. And do remember to document each method and generate a clickable jar that should be submitted along with the java sources and the javadoc. Exceptions must be caught using try/catch in the model or in the control with the corresponding throws in the model method. IMPORTANT NOTE.
