HSP45116-DB
The complex inputs may be changed by entering
hexadecimal values into the data windows. The contents of a
particular data window may be edited by depressing the
<Enter> key and using the arrow keys to position the cursor
on the hexadecimal character to be modified.
If file input is selected, the complex inputs are driven with
data from the specified file. On each clock the data windows
are updated with the complex sample down loaded from the
file. In this mode the complex input data windows may not be
manually updated.
Control Signals
The Control Signal portion of the control panel is used to
define the state of various control signal inputs to the
HSP45116. The logical state of a control signal is set by
using the space bar to toggle the signal state in the window
preceding the specified control signal. For the control signal
states displayed in the Control Panel to be active at the
HSP45116, the respective control signals must be jumpered
to the HSPEVAL’s CTL0-15 Bus via the HSP45116-DB's J3
jumper field as shown in the default jumper configuration
displayed in Table 1 (see Jumper Configuration Section).
The Control Signal descriptions are contained in the
HSP45116 Data Sheet.
Configuration Registers
The bottom of the control panel displays four data windows
which contain the hexadecimal values loaded into the
HSP45116's Center Frequency, Offset Frequency, Phase
Offset, and Time Accumulator Registers. The contents of a
particular configuration register may be updated by entering
a new hexadecimal value into the data window. The current
value in a window may also be edited by depressing the
<Enter> key and using the arrow keys to position the cursor
on the hexadecimal character to be modified.
The value entered into the data window is down loaded to the
HSP45116 after leaving the window via the arrow keys or
terminating an edit by the <Enter> key. If the data window is
associated with the Phase Offset Register, the 16-Bit
hexadecimal value is down loaded into the HSP45116's
Phase Input Register. If the data window is one of the three
32-bit windows associated with the Center Frequency, Offset
Frequency, of Timer Accumulator Registers, the 32-bit value is
loaded into the HSP45116's MS and LS Input Registers and
either ENCFREG, ENOFREG, or ENTIREG is asserted
respectively. Then, the enable signal is de-asserted and
registered on chip by another software generated clock. In
either Manual or Port Clock modes, a PC generated clock is
issued to ensure that the corresponding enable signal is
registered on chip (see HSP45116 Data Sheet). In either of
the other two clock modes, it is assumed that the clock rate is
high enough to register the enable signal before another
Configuration Register is updated. For proper operation, the
register enables, WR, and A0-1 inputs must be jumpered to
the HSP-EVAL's control bus and inputs via the J3 Control
Header as shown in the Default Jumper Configuration
(Table 1).
Help
Help windows are provided as a source of information for
control panel usage. The help window is activated by the F1
function key, and contains information based on the current
active data window.
Command Line Interface
As an alternative to the control panel, a command line
interface is provided which allows the user to control the
HSP45116-DB by issuing commands from the DOS prompt.
The commands perform basic I/O and configuration
functions by up or down loading data to the HSP45116
through the HSP-EVAL. The Command Line program has
the following usage:
