Functional Description
MVME2502 Installation and Use (6806800R96D )
86
4.2.12 Security Engine (SEC) 3.1
The integrated security engine of the P2020 is designed to off load intensive security functions
like key generation and exchange, authentication and bulk encryption from the processor core.
It includes eight different execution units where data flows in and out of an EU.
NOTE: The standard versions of the MVME2502 do not use the encryption enabled versions of
the P2020 processor.
4.2.13 Common On-Chip Processor (COP)
The COP is the debug interface of the QorIQ P2020 Processor. It allows a remote computer
system to access and control the internal operation of the processor. The COP interface
connects primarily through the JTAG and has additional status monitoring signals. The COP has
additional features like breakpoints, watch points, register and memory
examination/modification and other standard debugging features.
04 U29 Connected to INTA of the QUART. Programmed as
a discrete input or to generate IRQ11.
Also connected to pin P16 of the CPLD. (unused
input)
03 N24 Connected to pin P15of the CPLD
02 P29 Connected to Pin R16 of the CPLD. Programmed to
generate a IRQ09 interrupt to the CPU based on
contents of the CPLD GPIO2 interrupt register. For
more information see,
PLD GPIO2 Interrupt Register
on page 123 .
01 R26 Connected to INTA_N of the DS1337 Real Time
Clock (RTC). Programmed as a discrete input or to
generate IRQ08
00 R28 Connected to LED_P21[2] of the BCM5482S.
Programmed as a discrete input or to generate
IRQ07.
