axis-uart

AXI Stream UART

Features

• Parity: None, Even, Odd, Mark, Space
• Byte Size: up to 16 bits
• Stop Bits: One, Two
• Flow Control: None, RTS/CTS
• Static and Dynamic Configuration

Baudrate Calculation

Baudrate ~ aclk / prescaler_value Example: if aclk is 100MHz, and desired baudrate is 115200, then the prescaler value must be approximately equal ~868.

Dynamic Configuration

Use s_axis_config_* interface to dynamically configurate UART. Bits:

• [15:0] - prescaler
• [18:16] - parity (0 - none, 1 - even, 2 - odd, 3 - mark, 4 - space)
• [22:19] - byte_size (from 1 to 16)
• [23] - stop_bits (0 - one stop, 1 - two stops)
