PicoBlaze_Simulator_in_JS
DESCRIPTION
A web-based assembler for and emulator of Xilinx PicoBlaze.
Features
- Includes an assembler and an editor with support for (mostly) accurate syntax highlighting of PicoBlaze assembly language. That is, the syntax highlighting is accurate apart from the fact that the highlighter cannot tell whether the tokens `a`, `b`, and `c` are flags or hexadecimal constants.
- The assembler supports arithmetic expressions (including the ternary conditional `?:` operator), constants, if-else-branching and while-loops, and switching from the Xilinx-assembler-compatible mode in which unmarked numerical literals are interpreted as hexadecimal to the mode where they are interpreted as decimal.
- The assembler supports the `print_string` command to facilitate dealing with long strings (so that you don't have to print them character-by-character).
- You can download the hexadecimal file produced by the assembler (to try your program on real PicoBlaze). Unfortunately, for now, that does not work in WebPositive, and perhaps not even in Safari.
- Simulates UART (disabled by default), switches, 7-segment displays, and LEDs. Switches, 7-segment displays, and LEDs are rendered graphically using SVG.
- Works in Firefox 52 (on Windows XP) without polyfills, and in Firefox 47 (on ReactOS) with polyfills.
- Does not require a back-end to be hosted. The assembler and emulator are both written in JavaScript (not PHP) and run in the browser.
- Recently changed registers and flags are highlighted with a different background, to make it hard not to notice unexpected changes in registers and flags.
- If run on a server with PHP and MySQL enabled, the users can share their own PicoBlaze assembly programs.
- The emulator supports breakpoints. For now, it supports only permanent breakpoints, it doesn't support temporary ones.
This is an application that can also be fetched from https://sourceforge.net/projects/picoblaze-simulator/. It has been hosted in OnWorks in order to be run online in an easiest way from one of our free Operative Systems.
