In addition, there are either one or two blocks of dual-port SRAM in
the embedded stripe, depending on the device type. The outputs of
the dual-port memories can be registered. One of the ports gives
dedicated access to the PLD; the other port can be configured for
access by AHB masters or by the PLD. The width of the data port to
the PLD is configurable as ×8, ×16, or ×32 bits. For the larger devices,
the dual-port SRAM blocks can be combined to form a ×64-bit data-
width interface. This allows the designer to build deeper and wider
memories and multiplex the data outputs within the stripe.
External Memory Controllers
The Excalibur family provides two embedded memory controllers
that can be accessed by any of the bus masters: one for external
SDRAM, and a second for external flash memory or SRAM.
The SDRAM memory controller supports the following commonly-
available memory standards, without the addition of any logic:
I
I
An embedded stripe PLL supplies the appropriate timing to the
SDRAM memory controller subsystem. Users can program the
frequency to match the chosen memory components.
The EBI supports the interface to system ROM, allowing external
flash memory access and reprogramming. In addition, static RAM
and simple peripherals can be connected to this interface externally.
Embedded Peripherals
A single 16-Kbyte memory region in the embedded stripe contains
configuration and control registers, plus status and control registers
for the embedded peripherals. The region contains the following
modules:
