Chapter 1: Introduction
The processor(s) in the PS always boot first, allowing a software centric approach for PL system boot
and PL configuration. The PL can be configured as part of the boot process or configured at some
point in the future. Additionally, the PL can be completely reconfigured or used with partial, dynamic
reconfiguration (PR). PR allows configuration of a portion of the PL. This enables optional design
changes such as updating coefficients or time-multiplexing of the PL resources by swapping in new
algorithms as needed. This latter capability is analogous to the dynamic loading and unloading of
software modules. The PL configuration data is referred to as a bitstream.
1.1.1 Block Diagram
Figure 1-1 illustrates the functional blocks of the Zynq-7000 AP SoC. The PS and the PL are on
separate power domains, enabling the user of these devices to power down the PL for power
management if required.
