Really interesting article. Perhaps their biggest competitor is RMI who just bought Alchemy off AMD. They have an 8-core 32-thread SMT MIPS chip. Interesting to see all these new RISC start-ups working under the radar of the big boys ;-).

XLR732 Processor

The heart of the XLR732 processor consists of an innovative set of XLR™ cores enabling up to 32 threads or virtual CPUs (vCPUs™) in a single chip. The XLR architecture is built around eight XLR-enhanced MIPS64-compatible cores implementing fine-grained, 4-way multithreading combined with multi-level hierarchy of caches, autonomous accelerators, and point-to-point interconnects for data and message transfers.

The interconnects’ full-speed operation augment application scalability and closely integrate the high performance main memory controllers, level-2 caches, 10Gbps accelerated security operations, and accelerated networking interfaces to deliver a processing solution running at frequencies of 800MHz – 1.2GHz optimized for maximum throughput and workload efficiency.

RMI XLR732 Highlights:

* Operating Frequency 800MHz – 1.2GHz
* 8 Cores with 32 Threads (vCPUs™)
* 2MB of Banked 8-way L2 Caches
* Four Autonomous Security Acceleration Engines (SAEs) with 10Gbps capacity
* 4 x 36bit (144 bit) DDR I/II at 800MHz
* 2 x 10GE/SPI 4.2
* 4 x 1GEs
* 1605 BGA Package
