Task	REQUEST FOR PROPOSAL PORT Intel MCS BASIC-52 Interactive RTOS shell to Cypress PSoC 6 BLE Pioneer Kit                               Update: 5/28/18 08:46
1	Write interpreted syntax-checking ARM m4 assembler in Intel MCS BASIC-52. Input: Single instruction buffer or file contains text examples of all m4 instruction set operands. Include FP instructions. Example operands: 8 bits 01 16 bits 0123 32 bits 01234567 64 bits 012345789ABCDEF Tokenize [ 0, 1, 2, ...] symbolic opcode with linear search. Push operands, if any, on to operand stack. Assemble single instruction interactively with jump to instruction assembly module [subroutine]. View in binary or hex in output window. Interactive debug one instruction at a time. Debug global symbolic and local lables [$1: - $1, $2: - $2, ...] with batch input test file. Output: window, binary file. Write Visual BASIC .NET interactive emulator of Intel MCS BASIC-52 features. Use interactive emulator to debug assembler in Visual Studio.
2	Write ARM m4 disassembler in Windows 10 Visual BASIC .NET. Input: single opcode + operands or m4 binary source. Tokenize opcode [0, 1, 2, ...] with linear search. Invoke instruction module. Recover operands. Debug each opcode disassembly interactively. Then debug multiple instructions lines batch. Output: Instruction disassembly window. Text source file. Allow single step for batch file disassembly.
3	Write syntax-checking ARM m0+ assembler in Intel MCS BASIC-52. Input: Single instruction or file containing examples of all m0+ instruction operands. Example operands: 8 bits 01 16 bits 0123 32 bits 01234567 64 bits 012345789ABCDEF Output file: binary .txt Write Visual BASIC .NET interactive emulator of Intel MCS BASIC-52 features. Use toto debug assembler in Visual Studio. Input: Single instruction buffer or file contains text examples of all m4 instruction set operands. Include FP instructions. Example operands: 8 bits 01 16 bits 0123 32 bits 01234567 64 bits 012345789ABCDEF Tokenize [ 0, 1, 2, ...] opcodes with linear search. Push discovered operands, if any, on to operand stack. Assemble single instruction interactively with jump to instruction assembly module [subroutine]. View in binary or hex in output window.
4	Write ARM m0+ disassembler in Windows 10 Visual BASIC .NET. Input: single opcode + operands or m0+ binary source. Tokenize opcode [0, 1, 2, ...] with linear search. Invoke instruction module. Recover operands. Debug each opcode disassembly interactively. Then debug multiple instructions batch. Output: Instruction disassembly window. Text source file. Allow single step for batch file disassembly.
5	Write Intel MCS BASIC-52 emulator in Visual Studio Visual BASIC .NET .
6	Port Intel MCS BASIC-52 to m4 core [BASIC-P6M4] using using modules written in m4 assembler similar to modules written by John Katausky in 8051 assembler. Use MCS BASIC-52 stack structures: control stack, argument stack, internal stack. Implement MCS BASIC-52 line editor. Use Intel MCS BASIC-52 windows 10 emulator to debug.
7	Port BASIC-P6M4 to m0+ core.

Intel MCS BASIC-52 is an interactive RTOS shell.. Intel employee John Katausky wrote BASIC-52 and a floating point extension in assembler. Katausky promoted to VP for this work, late Mark Thompson reported. Thompson supplied 5-1/4 disk containing assember source code of BASIC-52. Forth is an interactive RTOS shell too. Original figforth 8080 programmers wrote the 8080 assembler in high level forth. Nautilis 1 metacompiler generated 8080 binary target from source code cross complied on a IBM PC. Clear advantage over implementing forth in assembler. Can ARM 4 and 0+ core assemblers be written in high level Intel MCS BASIC-52? If so, then it should be possible to generate PSoC 6 BLE interactive BASIC RTOS shell from source. RTOS shell would then contain an interactive/batch incremental compler/assembler. And would be extensible by adding new constructs in high level BASIC or assembler.

Interactive or batch? Real or virtual machine software technology? Interactive RTOSs/OSs require command interpreter[s]. Microsoft Windows command line interpreters (shells) such as COMMAND.COM , cmd.exe , 4DOS, 4NT and Windows PowerShell. [Wrote FORTH51 command line interpreters ENCLOSE and -FIND in 8051 assembler. And the syntax checking 8051 assembler too. Sandia labs job assignment.]
