Along with the other responses, here are
some additional things to note when comparing the 56F80x family (not
including 56824, 56F826 and 56F827) to TI's C24x and ADI's DashDSP
family...
- 'F80x devices do have ADC, 12-bit, and
they are configured as dual ADCs with seperate sample/hold circuits for
simultaneous conversions (so, TI may list faster single conversion time, but
utilizing the dual ADC feature for multiple conversions cuts down conversion
time for Mot DSP)
- The higher performance C240x devices (30-40
MIPS) and Motorola's 'F80x both run off 3.0-3.6V supply (3.3V
nominal), but the TI devices require a separate 5V supply to program the Flash;
Mot does not
- Motorola has loaded these DSPs with timers
which can be concatenated for 32-bit and 64-bit timer operation; I don't
believe TI or ADI offers this option
- TI's Third Party support is more focused
on their C54x family, with very little support for the C24x; Motorola's SDK
(Software Developers Kit) already contains drivers and application examples to
get you started right away
- Motorola's DSP56F801 has the option to
run off internal relaxation oscillator; competitor's do not
- Motorola offers feature rich DSP56F807--
60kx16 PFlash, 8kx16 Data Flash, 2kx16 PRAM, 4kx16 XRAM, 2kx16 Boot Flash, 2
SCI, 1 SPI, watchdog timer, 2 dedicated Quad Timers and 2 quad timers muxed
with quadrature decoders, 14 dedicated GPIO, 18 multiplexed GPIO, JTAG/OnCE,
2x6-ch 16-bit PWM, CAN 2.0A/B, low-voltage interrupt, external memory bus, 160
LQFP and MBGA
- ADI does offer small packages (28-pin)
and ROM versions; TI offers limited ROM devices; Motorola offers
Flash
For more information, you should contact a
local Motorola sales rep or distributor, and visit www.mot-sps.com.
Hope this is useful to you.

all,
I am new to this newsgroup as well as to DSP in general. Can you guys that have all the experience give me a comparison between the Motorola DSP56F80x and similar DSP's (40MIPS, 16bit fixed point) from TI and AD?
Thanks in advance...
