I seem to recall the ARM chips had a cache between the core and the I/O buss. I browsed some links to the Blackfin chips and wonder if this link indicates a more direct link between the core and the PPI and other I/O? http://www.analog.com/en/processors-dsp/blackfin/adsp-bf537/processors/product.html At 600MHz, these chips seem to scoot pretty well too. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
