Steraming width in TLM2

Recommended Posts

Hi Experts


Can any one explain the meaning of streaming width with some example.

The LRM does not have much explaination to this.

Few small example will be a great help.

Imagine you have a device such as a UART (serial port) with a transmit data register. Every time you write a byte to this register, it sends the data.


Now imagine you want to send 64 bytes through that stream with a single transaction. So you stream a payload with 64 bytes to the register address (SEND_ADDR) with a streaming width of 1. All 64 bytes are written to the single address.


If the streaming width were set to 64, then the bytes would go to SEND_ADDR+0, SEND_ADDR+1, SEND_ADDR+2, ... , SEND_ADDR+63. In other words, one address per data item.
