[sdiy] Re: [sdiy-interim] FLASH/JTAG based DSP?

[ezion]

Here are two I just learned about: Both AD and Freescale have FLASH
DSPs that look remarkably like uC both in peripheral features as in
price.
Freescale parts listen too DSP56F80x  and MC56F8xxx.
Analog Devices chimes in with ADSP-BF538Fxxxx.
The Freescale stuff goes in the 60 to 80 Mhz lane just like the ARM9.
However the AD Blackfin Flash parts seem to run quite a bit faster,
although from what I read so far you need to copy code to SRAM to go
full throttle?

Think I stick with the ARM9 for a while.
