Dear Zhongsheng,

A few years ago I designed a product based on the L307 (but I changed to
56311 later, and would now use the 56321 for a new design).

The Motorola-Freescale EVMs come with the CLAS software that includes an
assembler, linker simulator, C compiler, and debugger. I have not used
the C compiler, but am told that if you work at it, it can be useful.
All my work has been in assembly language using the CLAS tools and they
work pretty well. These software tools are free and available on-line at
freescale's web site.

I use a Command Converter that connects between the PC's parallel
printer port and the EVM (or your own target hardware). The object code
format is, I believe, *.CLD format.

If you are interested, I have a L307 (and a 311) EVM (software
included) for sale for $150 (150USD) plus shipping. I do not have an
extra Command Converter to sell.

I have no experience with an RTOS for the L307.

Best wishes,

Chris Moore

Hi,

I am new to DSP world and know nothing about the embedded software
development so far.

I am targeting for DSP56L307 chip. I am wondering if anyone who has
the development experience of this chip can give me highlights of the
development environment and RTOS that can run best on the chip. Is
CodeWarrior compatible with this chip? Do I have to buy a command
converter? what kind of file format (COFF?) the chip can support? Any
performance panelty if I write the DSP code in C rather than asm?

Thanks,

zhongsheng
