New Desktop Development Environment reaches out

Posted by Steve Revill Fri, 21 Feb 2020 22:39:00 GMT

Last year’s London show saw the snappily titled DDE29 becoming generally available.

Packing in some 300 changes, the main highlights are:

• Latest Norcroft C compiler
  • Code generation now tailored to use ARMv6/v7/v8 extended instructions where possible
  • Optimisations to substitute selected code sequences with ARMv6/v7/v8 media instructions where possible
  • Inline assembler updated to accept ARMv6/v7/v8 mnemonics
  • Literal pool reductions where available and enabled through use of MOVW+MOVT
  • New intrinsic functions to get access to operations not normally accessible from C
• ABC (the BASIC compiler) now supports hexadecimal entered in mixed case
• Revised User Interface Toolbox and ABC manuals plus detailed change logs for all the provided tools
• Library improvements to the TCP/IP library adds RFC2553 supporting functions, part of the TCP/IP bounty work getting ready for IPv6, and stronger type checking for all functions in the Toolbox library
• DDT (the desktop debugger) now uses the same disassembly engine as other tools, and can step the new instructions which the compiler emits
• Technical enhancements to AMU, CMHG, and ABC’s command line processing

At last! RISC OS is back on NOOBS

Posted by Steve Revill Thu, 25 Oct 2018 09:23:00 GMT

Great news! RISC OS is back in the list of Operating Systems supplied as a part of the Raspberry Pi NOOBS – New Out Of the Box Software. It dropped off the list a couple of years ago when our support for the Pi 3 took longer to appear than we’d hoped, but now it’s back!
