APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list (for example no bursts). Furthermore, it is an interface designed for a low frequency system with a low bit width (32 bits).
This was an early example of a medium-scale integrated circuit. Another popular chip was the SCN2651 from the Signetics 2650 family. An example of an early 1980s UART was the National Semiconductor 8250 used in the original IBM PC's Asynchronous Communications Adapter card. [5] In the 1990s, newer UARTs were developed with on-chip buffers.
AXI-Lite bus is an AXI bus that only supports a single ID thread per initiator. This bus is typically used for an end point that only needs to communicate with a single initiator device at a time, for example, a simple peripheral such as a UART. In contrast, a CPU is capable of initiating transactions to multiple peripherals and address spaces ...
UART/I²C/SPI columns - green cell means a dedicated peripheral, * yellow cell means a multi-feature peripheral that is chosen by setting configuration bits. Most USART peripherals support a minimum choice between UART or SPI, where as some might support additional choices, such as LIN, IrDA, RS-485.

To prevent preemption of its technologies by aggressive patenting, the Wishbone specification includes examples of prior art, to prove its concepts are in the public domain. A device does not conform to the Wishbone specification unless it includes a data sheet that describes what it does, bus width, utilization, etc. Promoting reuse of a ...
