The PBX-A9 baseboard is a highly integrated software and hardware development system based on the ARMv7-A architecture. It is supplied self-powered, in an ATX profile enclosure.
The Cortex-A9 processor subsystem is located on a custom daughterboard (HBI0183). The daughterboard cannot be removed and used separately from the PBX-A9 baseboard (HBI0182).
Used standalone, the baseboard serves as a fast multiprocessor software development platform with either two or three Cortex-A9 processors (CPU0 − CPU2) and a memory system in a structured ASIC running at near ASIC speed.
Used with FPGA-based RealView Logic Tiles, stacked on the baseboard, it enables custom AMBA 3 peripherals, processors, and DSPs to be added to the existing ARM development system.
The PBX-A9 is intended for development of both embedded and operating system based software for ARM processors. The ability to add Logic Tiles enables new hardware to be prototyped and validated, and drivers to be debugged.
The PBX-A9 includes:
a Cortex-A9 structured ASIC
a structured ASIC (Northbridge) with performance-critical peripherals
an FPGA (Southbridge) with additional peripherals
static and dynamic memory
integrated peripherals
a tile site to enable connection of RealView Logic Tiles
connectors for external peripherals and JTAG configuration and debug.
Figure 1.1 shows the top level system architecture of the baseboard.
The following sections introduce the major system components:
