Is AMBA AHB bus bandwith 16 times clock frequency??????

[vvmalode]

I have read that AMBA AHB bus bandwidth (in bps) is 16 times clock frequency. Is it true?

I read this in one of the ppt presentation downloaded from net. I want someone to confirm this.

If this is true then if clock frequency is 25MHz then can I assume bus bandwidth to be 400Mbps for my AMBA AHB bus

Waiting for your reply!!!!
Thanks in advance.

Hi,

I from my understanding, we can configure the AHB transaction in many modes like burst of 16, 8, 4, 2, single etc.
For example if we are configuring the burst of 16 with data width of 32 bits, which means in a single transaction there will be a transfer of 32*16 bits, within 16 clock cycles (here i am neglecting the initialization and the transfer is continuous without delay).
So we cant generalize the transfer rate. It depends up on the Data width (2, 4, 8, 16, 32, 64), frequency, modes of transaction (burst, single, etc)
