Thunderbolt Compute Module

The Thunderbolt compute module capitalizes on the AltiVec-based 500 MHz MPC7410 PowerPCs by supporting high-speed processing with high-speed memory and communication. SKY has implemented the level 2 cache in the processor to provide developers with both high performance compute and the I/O power to maximize total computational throughput. The Thunderbolt compute module uses four MPC7410 PowerPC processors to provide up to 16 GFLOPS of performance. Each processor has its own local bank of 256 or 512 MB of SDRAM that is accessed over the processor's 125 MHz local memory bus at 1 GB/sec. The memory of other processors on the module can also be accessed over the 1 GB/sec local bus. Memory on other modules is accessible through the 320 MB/sec SKYchannel interface.
