Data bus width

I need to calculate the total number of address lines of the peripheral. If it is 512 Mbyte and 16 bit databus width then ,as per my understanding the total number of address lines required will be 25 lines. 512 Mbytes = (2^20) x 2^ 9 = 2^ 29. The data bus is 16 bits so Address bus will be ( 2^29) / (2x2^3) = 2 ^ 25. So total of 25 lines ..The specified bandwidth (6400) is the maximum megabytes transferred per second using a 64-bit width.

RoHS 1 2 3 4 5 »The protocol allows the data bus to be 8, 16, 32, 64, 128, 256, 512, or 1024-bits wide. However, it is recommended that a minimum bus width of 32 bits is used. A maximum bus width of 256 bits is adequate for almost all applications. For read and write transfers, the receiving module must select the data from the correct byte lane on the bus.The width of the data bus can be 8 to 1024 bits and with programmable burst length, up to 256 data beats. There is also an optional Bytes To Transfer (BTT) mode which is useful for streaming data without knowing a prior the burst size. Computers then evolved, the size/width of the external data bus increased from 1 to 16, 32, and finally to the present data size/width of 64 conductors. The bigger and broader bus gives more room for data flow at a time, just as the addition of more drive lanes to a highway allows more movement of cars through a point in a given amount of timeTable 5-5.

This is especially apparent when the minimal length of protocol transaction becomes equal to, or even smaller than, the data bus width. Let's take 100Gbps Ethernet as an example here. The shortest allowed length of L2 Ethernet frame is 64B (512b). At the same time, a typical implementation of FPGA busTotal Addressable Memory = (2^ address bus width) * Data bus width. IE a machine with a 16 bit Data Bus and 32 bit address bus would have. (2^32)*16 bits of accessible storage. or 8GB – Do the math yourself to prove it. How important is the address bus and data bus? The width of these buses determines way memory is used. In layman terms, the data bus width means "How many conductors in parallel transmit ones and zeros simultaneously on the bus". A single conductor would have width of one bit, 16 conductors would have 16 bits and so on. And how it relates to throughput? Well, 32 bits is 4 bytes where as 16 bits is just 2 bytes. The Serial ATA bus [SATA] is the serial version of the IDE [ATA] spec. SATA uses a 4 conductor cable with two differential pairs [Tx/Rx], plus an additional three grounds pins and a separate power connector. Data runs at 150MBps [1.5GHz] using 8B/10B encoding and 250mV signal swings, with a maximum bus length of 1 meter.14 hours ago · Now suppouse you have a counter from 0 to N-1 number of sources.
