From 9fdd0ad0e78514feadd6ed356c765ea12a5d4158 Mon Sep 17 00:00:00 2001 From: Leonid Yegoshin Date: Wed, 27 Nov 2013 10:07:53 +0000 Subject: [PATCH] MIPS: Add support for interAptiv cores The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit.
