EXTERNAL MEMORY
The fourth on-chip memory system is the L2 SRAM memory
array which provides 128K bytes of high speed SRAM operating
at one half the frequency of the core, and slightly longer latency
than the L1 memory banks. The L2 memory is a unified instruc-
tion and data memory and can hold any mixture of code and
data required by the system design. The Blackfin cores share a
dedicated low latency 64-bit wide data path port into the L2
SRAM memory.
Each Blackfin core processor has its own set of core Memory
Mapped Registers (MMRs) but share the same system MMR
registers and 128K bytes L2 SRAM memory.
External (Off-Chip) Memory
The ADSP-BF561 external memory is accessed via the External
Bus Interface Unit (EBIU). This interface provides a glueless
connection to up to four banks of synchronous DRAM
(SDRAM) as well as up to four banks of asynchronous memory
devices, including flash, EPROM, ROM, SRAM, and memory
mapped I/O devices.
The PC133-compliant SDRAM controller can be programmed
to interface to up to four banks of SDRAM, with each bank con-
taining between 16M bytes and 128M bytes providing access to
up to 512M bytes of SDRAM. Each bank is independently pro-
grammable and is contiguous with adjacent banks regardless of
the sizes of the different banks or their placement. This allows
