- added software reset to the usart
- the three bootloaders now also perform a soft-reset of the USART at system start-up
- new testbench: outputs UART data to the simulator console
- added new features to the documentry |

minor edits!
- removed core_id / num_of_cores generics
- replaced by simple 16-bit user code generic - use it the way u like ;)
- bootloader now also displays user code
- doc updated (the new user code stuff) |

- changed base address of boot ROM - now 0xF000
- RAM can now be up to 60kB (instead of 56kB)
- added info about bootloader type to SYSCONFIG
- minor edits... |

- bugfix in SFU's "count set bits" function (it was counting the number of cleared bits... ;) )
- modified start-up code for you guys, who want to directly initialize the internal RAM with a program... DO THAT WITH CAUTION!!! |

new processor version!
- reduced IRQ channels from 8 to 4 (sufficient!)
- replaced SFU's swi option with "count set bits" function
- modified bootloader, doc, library files and example projects according to changes
- minor rtl modifications |

- documentary update
- modified bootloader (small issues)
- removed clock enable signal from CPU
- CPU register file is now true single-port (less HW requirements, easier control from FSM)
- recompiled version of image generator (for WIN64) |

- wishbone interface: device enable flag, timeout enable flag; timeout constrained to 256 cycles (wb_interface.vhd)
- bug-fix in wishbone library (neo430/neo430_wishbone.h)
- minor timer logic improvement (timer.vhd & usart.vhd)
- documentary update (new wishbone control register flags) |
