In ham radio we have twenty manufacturer all writing and producing their own LCD screens and menus. A nightmare.s Thy all started with DSP function then suddenly loads of investments into screens.
Just add a USB port to the machines and plug in a chromebook, which costs 155. Three hundred dollars save at the shack, money spent on pre and post analog for dealing with this chaotic atmosphere.
The DSP is simple, we need in and out DACs at 8 mHz, 16 bit. We need ar least 80 Mflops of fixed point 32 bit signal 'taps'. Add in a separate center frequency LO on output. Opens the market big time. Floating point does no good, if you did you Z transforms, everything should be scaled.
Your source code really is set of pure linear discrete inductance, capacitance and transconductance. There are no parasitics. We can generate assembly from Spice, then each DSP makerwrits thor own linker from Spice to DSP..
Code never changes across bands. The local oscillator mixes in the high precision interface to the antenna. We really want the isolation of the digital from the horrors of atmospheric RF static.
