bits within the 48-bit instruction to create more efficient and
compact code. The program sequencer supports fetching these
16-bit and 32-bit instructions from both internal and external
SDRAM memory. This support is not extended to the asynchro-
nous memory interface (AMI). Source modules need to be built
using the VISA option, in order to allow code generation tools
to create these more efficient opcodes.
On-Chip Memory
The processors contain varying amounts of internal RAM and
block can be configured for different combinations of code and
data storage. Each memory block supports single-cycle, inde-
pendent accesses by the core processor and I/O processor.
The processor’s SRAM can be configured as a maximum of
160k words of 32-bit data, 320k words of 16-bit data, 106.7k
words of 48-bit instructions (or 40-bit data), or combinations of
different word sizes up to 5M bits. All of the memory can be
accessed as 16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit
floating-point storage format is supported that effectively dou-
bles the amount of data that may be stored on-chip. Conversion
between the 32-bit floating-point and 16-bit floating-point
formats is performed in a single instruction. While each mem-
ory block can store combinations of code and data, accesses are
most efficient when one block stores data using the DM bus for
transfers, and the other block stores instructions and data using
the PM bus for transfers.
Using the DM bus and PM buses, with one bus dedicated to a
memory block, assures single-cycle execution with two data
transfers. In this case, the instruction must be available in the
cache.
nal memory address space of the processors. The 48-bit space
section describes what this address range looks like to an
instruction that retrieves 48-bit memory. The 32-bit section
describes what this address range looks like to an instruction
that retrieves 32-bit memory.
