If you use dual port ram you still have the cost of adding external boot memory. Using IDMA allows one to boot from host, in that the host loads the PM & DM in the dsp eliminating the need for an external flash or eprom to boot the dsp. Using this method, a part of the dsp's memory space can be set aside and used as a sort of shared memory. The down side to using the IDMA is that it limits your external memory space to just eight locations (two addresses per chip select) rashmi ranjana <> on 06/10/2001 21:50:06 To: cc: (bcc: Chuck Petras/SEL) Subject: [adsp] Using Dual-Port RAM hi, I was planning to use IDMA method in order to establish communication between ADSP-2188 and a host processor. At the same time my friend suggested that, using Dual-port RAM could be an alternative for communication between Host and ADSP. I would like to know what are the advantages and disadvantages of using the Dual-Port RAM method in my system Design.
