From b5872db4a2ebe7dbc7a5e4013ae8ee37f3de3b97 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 10 Jan 2008 19:16:17 +0100 Subject: [ARM] 4584/2: ARMv7: Add Advanced SIMD (NEON) extension support This patch enables the use of the Advanced SIMD (NEON) extension on ARMv7. The NEON technology is a 64/128-bit hybrid SIMD architecture for accelerating the performance of multimedia and signal processing applications. The extension shares the registers with the VFP unit and enabling/disabling and saving/restoring follow the same rules. In addition, there are instructions that do not have the appropriate CP number encoded, the checks being made in the call_fpe function.
