| Risc OS Stuff
|
| This software is for Acorn Risc OS compatible personal computers only. Some only for RiscOS on the BeagleBoard with Cortex-A8 cpu. Most old code was developed on a StrongARM Risc PC with Risc OS 4.02. Sorry PC/x86 users...this is not for you.

VFPBasic_Examples (29/08/2011)
Some applications to use with the VFP/NEON compatible BBC Basic Assembler done by TBA Software for the Beagle Board. It includes FracNEON and FracVFP (converted from my ExtASM versions) and a comparision of SQRT and SIN variants. To run the code you got to get the enhanced BBC Basic Assembler at TBA Software. UPDATE: Now the archive contains also an adaption of 'BiLiZo', my old Intro.

!MemSpeed (20/03/2011)
A Set of Memory Speed Benchmarks to find out what transfer rate can be achieved for different set ups regarding moving to and from RAM or VRAM. It's also using the ARM Neon unit on the Beagle Board with Cortex-A8 cpu, but versions for older ARM's are also included. I put some of the results in graphs here and here.

!FixFrac (26/09/2010)
A 32 bit fixed point arithmetic mandelbrot calculation demo, including boundary tracing, use of 64 bit multiply and benchmarking. Recently a special tuned 64 bit multiply version was added, also for direct comparison of the results to my x86 code and to last it longer for the latest BeagleBoard Cortex-A8 computers.
