![]() This instruction addressing to RAM for write or readģ: PC - Program Counter (Modern: IP - Instruction Pointer). ![]() This registers can be used for contain any dataĢ: MI - Memory Instruction. $ emuBOOB run -input="examples/multiply.asm" -output="exaples_target/multiply" -build Referencesġ: GPR- General Purpose Register. There are some examples of programs in examples directory. You will see version of emulator of 8008. Press enter to execute next instruction.This flag giving opportunity to execute instructions one by one with control This flag specifying that you would build input file and after that execute output file in emulator. Will be displayed more information about instructions and will display memory dump. $ emuBOOB run -input="project/src/main.asm" -output="target/my_app" -build This option is usefull only with -b flag, when you building before executing.Į. This is obligatory option, where you specify the path to the binary file or source code (see -b flag)Į. You will see version of compiler for 8008.Įmulator can execute binary made obly by emuBOOB's compiler. Will be displayed your assembly code and after opcodes for i8008. $ emuBOOB build -input="project8008/src/main.asm" -output="target/my_app" With this option you can specify path and name of output bianry file.Į. $ emuBOOB build -input="project8008/src/main.asm" This is obligatory option, where you specify the path to the source file.Į. This would make bianry file in same directory, which after you can execute in emulator asm files with very strcit rules.įor build your assembly code for i8008 run this: Ubuntu / Debian $ sudo apt-get install cargoĮmuBOOB's compiler supporting only.Try run: $ curl -proto '=https' -tlsv1.2 -sSf | sh ![]() YOU SHOULD HAVE RUST AND CARGO TO INSTALL THIS EMULATOR Rust Installation You can write values in different bases, for specify base you should write after value ( 'd', 'h', 'o', 'b') for decimal, hexadecimal, octal and binary accordingly.Calling or jumping to a label, the label name should starts from ampersand ( &).All values/labels which is needful for the instruction should be on same line and separated with whitespace from instruction.Label should be before labaled block on another line.All instructions should be shifted on one tab of 4 spaces.First line is with CPU command and value 8008 (see examples).EmulatorĮmulator is very close to real structure and ecosystem of MCS-8.Įmualator has pretty dump output of CPU and Memory. For this use RAM RAMĪfter finishing executing programme all data from RAM would be erased. PROM is used to contain programme's code. In MCS-8 memory block is separated into 2 parts. Try to prevent this overflow! Instruction Set If you overflow stack level it would erase first levels. SP is 3 bit length and you can't change its value. Subsequently, it has only 7 levels of deepnest. ![]() I8008-1 is impoved version of standart i8008 with decreased cycle time (from 20 µs to 12.5 µs).įuther in the text i8008-1 will be named just 8008 Registers NameĪLU can do arithmetic and logical operations:ĪDD, ADD with carry, SUBTRACT, SUBSTRACT with borrow, AND, EXCLUSIVE OR, OR, COMPARE, INCREMENT, DECREMENTĪll ALU operations have influence on flags' flip-flops.īut INCREMENT and DECREMENT don't touch C (carry) flag. | translator.rs | -> | OUTPUT | | | mem.rs | /- | cli.yaml | | dictionary.rs | | INPUT | | cpu.rs | | mcs.rs | | | dump.rs | Here is how to use it: labe_name, where index can be 'h' or 'l' for high and low parts respectively.+-+ +-+ +-+ +-+ In addition, you are able to "index" label to get access to its low or high part of address. If the number does not have a prefix, the number shall be determined as decimal. The list of the prefixes is: $ for hex values, % for binary and # for decimal. Numbers in this assembler can have a prefix, which determines the number's base. If you want to declare a constant, you must write a keyword "define", then the constant's name and finally its value, which should fit in 8-bit. The assembler supports labels and constants. If the second argument is not presented, the name of the output file shall be 'a.bin'. The running of this program requires at least one argument - an input file nime with the programs text itself the second argument is an output file name and is optinal. Otherwise all contents of this line will be ignored, excluding the label. A simple assembler for the Intel 8008 CPU. There should be only a label itself in a line. If the second argument is not presented, the name of the output file shall be "a.bin". The running of this program requires at least one argument - an input file nime with the program's text itself the second argument is an output file name and is optinal.
