Is this thread worth a thumbs up?

Hi, I would go to the Analog Devices website and look at the EZKIT for the TS201 first. It shows how to connect two TS201s through both the External Port and through the Link Ports. The hardware reference manual goes into more detail on how arbitration between processors works in the External Port chapter. Going through the external port allows up to 8 TS201's to be connected together with a programming model that enables any one to access any other processor's internal resources. Each CPU would have a unique hard wired address (0 to 7). Link ports can be used for point to point communications between two CPU's. The Link Port chapter provides additional information on how that peripheral works. Some multiprocessor systems use just Cluster Bus (ie External Port connection), some use just link ports, and some use a mix of the two. The first chapter on Architecture provides an overview on how MP systems can be configured. Flash booting is described in several chapters. External Port talks about connecting the flash device to the TS201, the DMA chapter talks about the special DMA transfer mode that performs the 8 bit to 32 bit packing, and the System Design chapter talks about different boot modes and how the boot process functions. ADI provides example code that sets up the DMA and External Port to flash an application into the flash device, as well as boot kernels (code that is booted first and then extracts your application from the flash device and transfers to memory) for each boot method.
