>What frequency is the ARM processor? The phone shows ARM720 no freq. I'm going to have to guess around 100 Mhz. I ran the same code on an XSCALE ARM 400 mhz. Toshiba e740. Runs about .33 -> .4x realtime. This is the using the generic fixed point defines. Around 5 times faster than I am seeing with the Orange SPV e100. I am using the 1.1.3 codebas...

Hello Greg If money isn't a problem Intel has an optimized compiler for eVC and XScale processors http://www.intel.com/software/products/compilers/techtopics/PCA_Optimization_WP.pdf If you have any luck getting the eVC compiler closer to realtime I'd really like to know. I'm still far from realtime when using Speex 1.1.3 on a HP iPAQ (Intel pxa255). Best regards Bjoern D.

...mpiler is going to be enough. I tried perl scripting the output of a linux gcc cross-compiler to convert into something the assembler under eVC would consume. It errors on all the MAC type of instructions. I looked at www.arm.com (I never knew there could be so many arms) It does not look like the ARM720 has the MAC instructions. It also lists 75Mhz and 100Mhz as possible frequencies. (I'm still hoping for 100 :-) I have started to look at reducing complexity by removing all perceptual filters in the encoder. It sounds ugly but my fallback is GSM 610. I'm open to any other ideas to cut C...

Target is Spv & Nokia phones ARM and also ipaq ARM. With the generic fixed point at complexity 0 I am still about 1.6x realtime for narrowband. The MS eVC compiler does not support inline assembler, only separate assembler functions. Does anyone have a feeling on whether a 2x speedup is possible if I hand tune a few functions? -greg. --- >8 ---- List archives:
