Input Select/Format Block
Each front end block and the level detector block contains an
input select/format block. A functional block diagram is
provided in the above figure. The input source can be any of
the four parallel input busses (see
Section
Table 1, IWA *000h) or a test register loaded via the
processor bus (see
Microprocessor Interface Section
register F807h).
Microprocessor Interface
, GWA
The input to the part can operate in a gated or interpolated
mode. Each input data bus has an input enable (ENIx, x = A,
B, C or D). In the gated mode, one input sample is
processed per clock that the ENIx signal is asserted (low).
Processing is disabled when ENIx is high. The ENIx signal is
pipelined through the part to minimize delay (latency). In the
interpolated mode, the input is zeroed when the ENIx signal
is high, but processing inside the part continues. This mode
inserts zeros between the data samples, interpolating the
input data stream up to the clock rate. On reset, the part is
set to gated mode and the input enables are disabled. The
inputs are enabled by the first global SYNCI signal or
SYNCIx signal, where X = 0, 1, 2 or 3.
The input section can select one channel from a multiplexed
data stream of up to eight channels. The input enable is
delayed by zero to seven clock cycles to enable a selection
register. The register following the selection register is
enabled by the non-delayed input enable to realign the
processing of the channels. The one-clock-wide input enable
must align with the data for the first channel. The desired
channel is then selected by programming the delay. A delay
of zero selects the first channel, a delay of one selects the
second, etc.
The parallel input busses are 17 bits wide allowing for up to 16
bits of fixed-point data or 14 bits of mantissa with three bits of
exponent for floating-point data. The input format may be twos
complement or offset binary format in either fixed or floating
