According to the datasheet for the BF537/BF534/BF536 each chip is able to support three 16-bit MACs, but the Analog Devices spreadsheet comparison tool states:
BF534 500MHz 1000MMACS
BF536 400MHz 800MMACS
In fact, the details for the BF537 are all missing but presumably with a clock frequency of 600MHz it should support 1200MHz.
However, if the datasheet is true and they really do support three MACs the table should be:
BF534 500MHz 1500MMACS
BF536 400MHz 1200MMACS
BF537 600MHz 1800MMACS
Can anyone explain this to me?
I think this a mistake in datasheet. all Blackfin processors share the same Core and all have two MAC units.
Three 16-bit MACs is definetly wrong. All Blackfin derivatives feature two 16-bit MACs.
For complete "correct" information on the Blackfin core, see "BLACKFIN PROCESSOR CORE" on page 4 of the data sheet.
