The SCP3 Board, also is called CPV3, is functionally update of a standard SCP and SCP2 Board, which
its performance increases dramatically. It is required for certain purchased scan options.
The following is the functional and performance enhancements over the CPV-3060 (SCPII) assembly:
• Compute performance: the SCPIII processor operates with a core clock of 667 MHz, compared to the
50MHz processor clock on the CPV-3060 processor
• Memory bus performance: the SCPIII processor hosts DDR2 SDRAM components on a dedicated
167MHz bus, with a raw bus transfer capacity of ~21 Gb/s, as compared to the 2.1 Gb/s raw bus
transfer capacity of the 66 MHz SDRAM components on the CPV-3060
• Memory array capacity: the SCPIII processor offers 64 – 512 Mbyte capacity at the main memory
array, compared to the 64 – 128 Mbyte capacity offered on the CPV-3060. The RAM configuration for GE
part is 256M.
• Front panel Ethernet port: the SCPIII hosts a 10/100/1000BaseT port as compared to the
10/100BaseTX Ethernet port on the CPV-3060
• CANBus interface ports: SCPIII provides two front panel CANBus 2.0 interfaces on the main board in
place of the ESD Electronics PMC331-1 CANBus controller module provided with the CPV-3060.
All front panel and primary backplane I/O functions of the SCP2 are maintained on the new board
except for the rear-access SMC port, which is not supported on the newer PowerQUICC processors.
SCP3 has one PMC site and provides two on-board CANBus 2.0 interface controllers in place of the
second PMC site provided on the SCP2. The SCP3
’ s internal hardware architecture is implemented
around a new MPC8360 PowerQUICC II Pro processor with a 667 MHz core clock.
The middle white cable, equipped with the male RJ-45 connector, provides an Ethernet link between
the Host and the SCP. During a TPS Reset data is transferred to the SCP via this link.
The bottom cable, equipped with an RJ-45 connector, provides a service RS-232 serial link between the
SCP and the Host via the Term Server.
