support a generic Operating System The subsystem is replicated twice so both processors have the same memory map.
This structure enables a true symmetric multi-processor architecture were both
processors can simultaneously execute the same OS (all interrupt sources are handled
by both processors) All internal peripherals are shared, allowing flexible and efficient software partitions. High aggregate throughput can be sustained by splitting critical tasks either onto
additional CPUs and optional hardware accelerator engines. Both processors are equipped with ICE and ETM configurable debug interfaces. for

System Controller clock SCLK is driven by a low speed oscillator (nominally 32768 Hz).
When either a FIQ or an IRQ interrupt is generated (through the VIC) the system enters
DOZE mode. Additionally, the operating mode setting in the system control register
automatically changes from SLEEP to DOZE. DOZE mode: In this mode the system clocks, HCLK and CLK, and the System
Controller clock SCLK are driven by a low speed oscillator. The System Controller
moves into SLEEP mode from DOZE mode only when none of the mode control bits
are set and the processor is in Wait-for-interrupt state. If SLOW mode or NORMAL
mode is required the system moves into the XTAL control transition state to initialize the
crystal oscillator. SLOW mode: During this mode, both the system clocks and the System Controller
clock are driven by the crystal oscillator. If NORMAL mode is selected, the system goes
into the "PLL control" transition state. If neither the SLOW nor the NORMAL mode
control bits are set, the system goes into the "Switch from XTAL" transition state. NORMAL mode: In NORMAL mode, both the system clocks and the System Controller
clock are driven by the PLL output. If the NORMAL mode control bit is not set, then the
system goes into the "Switch from PLL" transition state.
2.19 Clock and reset system
The clock system is a fully programmable block that generates all the clocks for the
SPEAr600.
The default operating clock frequencies are: Clock @ 333 MHz for the CPUs. Clock @ 166 MHz for AHB bus and AHB peripherals. (PLL1 source) Clock @ 83 MHz for, APB bus and APB peripherals. (PLL1 source) Clock @ 100-333 MHz for DDR memory interface. (PLL1, PLL2 source) Clock @ 12 MHz, 30 MHz and 48 MHz for USBs (PLL3 source)
The above frequencies are the maximum allowed values.
All these clocks are generated by three PLLs.
PLL1 and PLL2 sources are fully programmable through dedicated registers.
The clock system consists of 2 main parts: a multi clock generator block and two internal
PLLs.
The multi clock generator block, takes a reference signal (which is usually delivered by the
PLL), generates all clocks for the IPs of SPEAr600 according to dedicated programmable
registers.
SPEAr600 Architecture overview
Doc ID 16259 Rev 3 21/97
Each PLL uses an oscillator input of 30 MHz to generate a clock signal at a frequency
corresponding to the highest of the group. This is the reference signal used by the multi
clock generator block to obtain all the other required clocks for the group. Its main feature is
electromagnetic interference reduction capability.
The user can set up the PLL in order to modulate the VCO with a triangular wave. The
resulting signal has a spectrum (and power) spread over a small programmable range of
frequencies centered on F0 (the VCO frequency), obtaining minimum electromagnetic
emissions. This method replaces all the other traditional methods of EMI reduction, such as
filtering, ferrite beads, chokes, adding power layers and ground planes to PCBs, metal
shielding and so on. This gives the customer appreciable cost savings.
In sleep mode the SPEAr600 runs with the PLL disabled so the available frequency is 30
MHz or a sub-multiple (/2, /4, /16 and /32) or 32 KHz.
PLL3 is used to generate the USB controller clocks and it is not configured through
registers.
2.20 Vectored interrupt controller (VIC)
Each ARM Subsystem of SPEAr600 offers Vectored Interrupted Controller (VIC) blocks,
providing a software interface to the interrupt system.
Acting as an interrupt controller, the VIC determines the source that is requesting service
and where its interrupt service routine (ISR) is loaded, doing that in hardware.
In particular, the VIC supplies the starting address, or vector address, of the ISR
corresponding to the highest priority requesting interrupt source.
Main features of the VIC are listed below: Support for 32 standard interrupt sources (a total of 64 lines are available for each CPU
from its two daisy-chained VICs). Generation of both Fast Interrupt request (FIQ) and Interrupt Request (IRQ. IRQ is
used for general interrupts, whereas FIQ is intended for fast, low-latency interrupt
handling. Support for 16 vectored interrupts (IRQ only); Hardware interrupt priority FIQ interrupt has the highest priority followed by vectored IRQ interrupts, from vector 0 to vector 15 then non-vectored IRQ interrupts with the lowest priority Interrupt masking/ interrupts request status Software interrupt generation
2.21 General purpose timers
SPEAr600 provides five general purpose timers (GPTs) acting as APB slaves.
Each GPT consists of 2 channels, each one made up of a programmable 16-bit counter and
a dedicated 8-bit timer clock prescaler. The programmable 8-bit prescaler performs a clock
division by 1 up to 256, and different input frequencies can be chosen through SPEAr600
configuration registers (frequencies up to 83 MHz can be synthesized).
Architecture overview SPEAr600
22/97 Doc ID 16259 Rev 3 wo different modes of operation are available: Auto-reload mode, an interrupt source is activated, the counter is automatically cleared
and then it restarts incrementing. Single-shot mode, an interrupt source is activated, the counter is stopped and the GPT
is disabled.
2.22 Watchdog timer
The ARM watchdog module consists of a 32-bit down counter with a programmable time-out
interval that has the capability to generate an interrupt and a reset signal on timing out. The
watchdog module is intended to be used to apply a reset to a system in the event of a
software failure.
2.23 RTC oscillator
The RTC provides a 1-second resolution clock. This keeps time when the system is inactive
and can be used to wake the system up when a programmed alarm time is reached. It has a
clock trimming feature to compensate for the accuracy of the 32.768 kHz crystal and a
secured time update.
Main features: Time-of-day clock in 24 hour mode Calendar Alarm capability Isolation mode, allowing RTC to work even if power is not supplied to the rest of the
device.
2.24 Reconfigurable array subsystem connectivity (RAS)
The Reconfigurable Logic Array consists of an embedded macro where it is possible to
implement a custom project by mapping up to 600k equivalent standard cells. The user can
design custom logic and special function using various features offered by the
Reconfigurable Logic Array and by the SPEAr600 system listed here below. 4 AHB bus master interfaces 5 AHB bus slave interfaces Dedicated interface with CPU1 to customize the Tightly Couple Memory Dedicated interface with CPU1 to customize the Coprocessor Dedicated interface with CPU2 to customize the Tightly Coupled Memory Interfaces towards a dedicated 130 kB Memory Array Subsystem provided of functional

2.25 External Port Controller (EXPI I/F)
The port controller is a socket communication interface between the SPEAr600 and an
external FPGA device; it implements a simple AHB bidirectional protocol used to compress
a couple of std AHB master/slave bus onto 84 PL_GPIOs and 4 PL_CLK primary signals.
Caution: PL_GPIO pins are not configurable by software.
ST provide a symmetric port controller logic solution to be embedded inside the external
FPGA with the purpose of interfacing the EXPI bus directly and decompressing the same
pair of AHB master/slave ports on the FPGA side in order to interconnect the customer logic
as follows (more slave and master agents can be connected to the EXPI):
SPEAr600_AHB-master >> FPGA_AHB-slave
SPEAr600_AHB-slave << FPGA_AHB-master (AHB-full)
The EXPI interface is based on two main groups of signals: AHB bidirectional signal bus driven alternatively from the SPEAr600 and FPGA side. Unidirectional signals continuously driven from both the SPEAr600 and FPGA sides. able 36: EXPI - pad signal assignment lists the EXPI signal names. Further details in these
signals are given in the SPEAr600 user manual (UM0510)
