Wanted: I2C RAM pre-loader VHDL module

Started by scd July 14, 2005
Hi,

Since the Actel RAM modules cannot be preloaded a program time,
I need a module that will read data from an I2C serial EPROM and
load up the block RAM.

Actel has an ap note on doing this, but they did not include any
VHDL code.  I hate to re-invent the wheel.. does someone have
a RAM pre-loader module to share?

Thanks in Advance,
Scott                              scd -at- teleport -dot- com

dont be lazy and just download the vhdl source code from Actel website, its there! Antti

I'm a big I2C fan but in this case I'd go for SPI. The SPI is simpler and faster. Some people have made very large serial memories and I note that they have chosen SPI. When transferring a lot of bytes, a few microseconds on each soon adds up...
