Data Transfer Rate

32-bit microprossor
16 bit external data bus driven by an 8 MHz input clock
bus cycle: minimum duration equals 4 input clock cycles

What is the maximum data transfer rate across the bus that this microprocessor can sustain in bytes?

This is a common bandwidth question, but with a twist: "a bus cycle whose minimum duration equals four input clock cycles".

The fact that this microprocessor is 32-bit is unnecessary info for this question.

The info we really need is the external bus width (16-bit), the CPU clock speed (8MHz), and the fact that the external bus clock cycle ...
