1The reduced instruction set computer (RISC) processor, also known as the intelligent stor- age peripheral (ISP) controller, is the heart of the adapter. The RISC processor is a single integrated ASIC (application specific integrated circuit) that contains the processing power required to run the Fibre Channel and FCoE protocols. The RISC processor also interfaces the host bus
2The static random access memory (SRAM) provides the runtime memory required for the adapter operations. The SRAM is where the firmware is downloaded when the adapter is powered up. The RISC processor (see 1) accesses the SRAM to process the firmware instructions. In addition, the SRAM stores the runtime context of various I/O operations in progress.
