OMAP-L139 Floating Pt?

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

1. I believe the answer is no, but can you tell me if the ARM926 core within the OMAP-L138 part has floating point capabilities?

2. Is there a note that describes the differences between the non-IEEE Neon floating point and the VFPv3 IEEE-compliant co-processor?

On OMAPL138 SoC, the ARM core is ARM9EJS, a fixed point processor with no floating point capability.

On C6A8168 SoC, the ARM core is a Cortex A8 with a Vector Floating Point unit and Neon SIMD coprocessor. They both share the same register banks, but VFP produces IEEE-compliant results due to the type of instructions that it provides. Details about Neon and VFP in A8 is at http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0344b/ch16s06s05.html
