Platform Baseboard for ARM926EJ-S

The Platform Baseboard for ARM926EJ-S provides an AMBA™ Multi-layer AHB prototyping environment. At the heart of the board is a highly integrated development chip which is based on the ARM926EJ-S platform architecture. External bus interfaces on the development chip, which enable bus layers inside the chip to be routed off-chip, provide access to the multiple internal bus layers of the Platform architecture for expansion.

Features of the Development Chip

• ARM926EJ-S processor, Jazelle^® Java acceleration hardware and DSP extensions
• 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
• Peripherals essential for operating system support, including JTAG run-control and Trace ports

The development chip integrates high performance IP such as memory and DMA controllers and the ARM VFP9-S coprocessor around the ARM926EJ-S core. The vector processing capability of the ARM VFP9-S coprocessor offers increased performance for imaging applications such as scaling, 2D and 3D transforms, font generation, and digital filters. The development chip also includes an implementation of the ARM MOVE coprocessor which significantly improves the motion estimation capability required for applications like MPEG encode through hardware assistance for sum-of-differences (SAD) calculations.
