BCM1250 system
Microprocessor operates at an internal clock speed of 700 MHz.
–
Hardware logic to interconnect the processor, double data rate synchronous dynamic
–
random-access memory (DDR-SDRAM), lightning data transport (LDT) bus, the generic PCI
bus, and three direct-interface Gigabit Ethernet interfaces.
Cache memory
The NPE-G1 has two levels of cache: primary and secondary cache that are internal to the
microprocessor with secondary unified cache for data and instruction.
The NPE-G1 uses DDR-SDRAM for providing code, data, and packet storage.
Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis.
