7.2.2.1 Working Registers
The datapath contains six primary working registers, which are
accessed by CPU firmware or DMA during normal operation.
Table 7-1. Working Datapath Registers
7.2.2.2 Dynamic Datapath Configuration RAM
Dynamic configuration is the ability to change the datapath
function and internal configuration on a cycle-by-cycle basis,
under sequencer control. This is implemented using the 8-word
x 16-bit configuration RAM, which stores eight unique 16-bit wide
configurations. The address input to this RAM controls the

These are sources and sinks for
the ALU and also sources for the
compares.
These are sources for the ALU
and sources for the compares.
These are the primary interface
to the system bus. They can be a
data source for the data registers
and accumulators or they can
capture data from the accumu-
lators or ALU. Each FIFO is four
bytes deep.
