- 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) |
