ug585-Zynq-7000-TRM.pdfを読んでいる中で出てくるAPBについて調べてみた。

The latest AMBA 4.0 specification defines five interfaces:

• Advanced eXtensible Interface (AXI)
• Advanced High-performance Bus (AHB)
• Advanced System Bus (ASB)
• Advanced Peripheral Bus (APB)
• Advanced Trace Bus (ATB)

APB connects to AHB and provides a low bandwidth and register interfaces for peripherals like serial ports. It is similar to AHB but less complex, requiring fewer transistors to implement. It doesn’t support transactions such as burst mode and targets smaller width interfaces.

low bandwidth, transactionなし。
