RealView Versatile/PB926EJ-S

High performance platform with Jazelle, DSP and MBX

The Versatile Platform Baseboard for ARM926EJ-S provides means of prototyping advanced 3D graphics platforms making use of ARM and PowerVR MBX cores. It also supports the MOVE coprocessor, for MPEG encode acceleration, Jazelle for Java acceleration and a Vector Floating Point (VFP) coprocessor for high speed 3D graphics transformations.

The core of the board is a highly integrated ARM926EJ-S based chip specifically designed for the platform, and incorporating much of the IP in silicon.

Development Chip Features

The development chip on the board features the following:

• ARM926EJ-S processor
• Jazelle Java acceleration hardware
• DSP extensions
• PowerVR MBX 3D Graphics accelerator
• MOVE coprocessor, hardware acceleration for MPEG encode
• Vector Floating Point (VFP) coprocessor, hardware assist for floating point arithmetic
• Off chip AHB bridges and system monitor for cycle accurate system prototyping
• Memory sub-system including DMA controller with a choice of static and dynamic memory and boot options
• Vectored interrupt controller for higher performance interrupt handling
