COMMAND DESCRIPTION
PF
INPUT FILE
OUTPUT Down loads complex samples stored in the file specified by Argument #1 into the
FILE
HSP-EVAL Registers driving the Real and Imaginary Input Buses of the
HSP45116-DB, clocks the data into the part, and stores the complex output to the
file specified by Argument #2. The input and output file formats are specified in Ap-
pendix A. See Notes 3, 4 and 5.
CK
Issues software generated clock pulse to HSP45116-DB by toggling the CTL0 bit in
the HSP-EVAL’s CTL0-15 Register. See Note 4.
RD
Reads data on the HSP45116-DB’s RO0-15 and IO0-15 outputs and prints data to
screen. See Note 4 and 5.
SM
Displays signal mapping between the CTL Control Register and the HSP45116
control inputs (assumes default jumper configuration shown in Table 1).
CR
Displays current state of CTL Control Register.
PC
Displays the printer port and HSP-EVAL board address that the NCOM_CMD pro-
gram is using for communication between the PC and the HSP-EVAL. The HSP-
EVAL board address is set by inserting a jumper in the ADDR0-7 positions of it’s J4
Jumper Field.
P#
PORT NUMBER
BOARD Change The Printer Port And HSP-EVAL Board Address that the NCOM_CMD Pro-
(1-3)
ADDRESS gram is using for communication between the PC and the HSP-EVAL to those specified
(0-7)
in Arguments 1 and 2. The HSP-EVAL Board Address is set by inserting a Jumper in
the ADDR0-7 positions of it’s J4 Jumper Field.

List available commands together with a brief description.
NOTES:
1. The CF, OF, TI commands load the specified 32-bit value into the HSP45116’s MS and LS input registers. After the configuration data has been
loaded into the MS and LS Registers, the corresponding enable, ENCFREG, ENOFREG, or ENTIREG is asserted. The enable signal is then reg-
istered on chip by a single software generated clock provided a jumper is inserted at the CTL0 position of the J4 jumper field on the HSP-EVAL.
Otherwise, it is assumed that the selected clock source is fast enough to register the enable signal prior to a subsequent load of one of another 32-
bit configuration register. The register enables, ENCFREG, ENOFREG, and ENTIREG must be jumpered to the CTL Control Bus as in the default
configuration shown in Table 1.
2. When commands are issued to load registers internal to the HSP45116, it is assumed that the microprocessor interface signals, WR and A0-1
are jumpered to the CTL0-15 bus as in the default configuration shown in Table 1.
3. If the complex input buses of the HSP45116-DB are to be driven by the HSP-EVAL’s Input Registers 1 and 2, their outputs must be enabled by
placing jumpers in the OE_BUS1 and OE_BUS2 positions of the J4 jumper field on the HSP-EVAL.
4. This command is only valid if a software generated clock source has been selected by inserting a jumper in the CTL0 position of the HSP-EVAL’s
J4 jumper field.
5. Commands required to read data on the HSP45116-DB’s complex outputs only function properly if the output of the shift register is selected for
reading by inserting a jumper in the SR_RD position of the HSP-EVAL’s J4 jumper field.
The Command specifies 1 of 14 actions to be taken, and the
Arguments (ARG1, ARG2) represent additional data
required by the command. For example, the HSP45116's
Center Frequency Register would be loaded with a value of
40000000(HEX) by typing:
NCOM_CMD CF 40000000 <Enter>
A summary of the command set is contained in Table 2.
Proper operation of the Command Line software is ensured
if the default jumper configurations for the HSP45116-DB
and the HSP-EVAL shown in Table 1 and Figure 2 are used.
However, modifications to this configuration may be required
depending on the clock source and the mode of operation.
The Command Line Interface gives the user the ability to
control the evaluation board set via DOS batch files or
system calls from a programming language. The
NCOM_CHK.BAT file discussed in the System Test Section
is an example of how the Command Line program might be
used in a DOS batch file.
Signal Headers
The HSP45116-DB maps the NCOM's inputs and outputs to
three 50-pin signal headers, J1-J3. The signal headers are
used to connect the NCOM’s I/O and control pins to the
HSP-EVAL’s I/O and control busses through three 50
position connectors. The Control Panel and Command Line
interface software control the operation of the HSP45116-DB
by up or down loading data to registers on-board the HSP-
EVAL which drive or monitor the I/O and control busses.
The J1 Input Header maps two 16-bit busses to the real and
imaginary inputs of the HSP45116, RIN0-15 and IMIN0-15.
In addition, a bidirectional clock line is routed to this header
as shown by the signal map in Table 3. When mated with the
J1 connector on the HSP-EVAL, the HSP45116's real and
imaginary inputs map to the HSP-EVAL's Input Bus 2 and 1,
IN2_0-15 and IN1_0-15, respectively.
