TILE64™ PROCESSOR FAMILY
The TILE64™ family of multicore processors delivers immense compute performance to drive the latest generation of embedded applications. This revolutionary processor features 64 identical processor cores (tiles) interconnected with Tilera's iMesh™ on-chip network. Each tile is a complete full-featured processor, including integrated L1 & L2 cache and a non-blocking switch that connects the tile into the mesh. This means that each tile can independently run a full operating system, or multiple tiles taken together can run a multi-processing operating system like SMP Linux.
The TILE64™ processor family slashes board real estate and system cost by integrating a complete set of memory and I/O controllers, thus eliminating the need for an external North Bridge or South Bridge. It delivers scalable performance, power efficiency and low processing latency in an extremely compact footprint.
With a standard ANSI C and C++ programming environment, developers can leverage their existing software investment as well as utilize the vast body of Open Source code available. Tiles can be grouped into clusters to apply the appropriate amount of horsepower to each application. Since multiple operating system instances can be run on the TILE64™ simultaneously, it can replace multiple CPU subsystems for both the data plane and control plane.
