Hardware and Software Architecture
Overview
This section describes the hardware and software modules of the radio and
their interaction in the functioning of the radio.
2.4.1
Hardware Architecture
The electrical hardware of the radio is implemented on a main board inside
the radio body and a control-head board inside the control head.
For a detailed description and block diagrams of individual circuits, refer to
“Circuit Descriptions” on page 21
.
Main Board
The main board inside the radio body includes the following circuitry:
■
transmitter
■
receiver
■
frequency synthesizer
■
digital board with a RISC processor and custom logic (implemented on
an FPGA), memory, and a DSP
■
CODEC and audio
■
interface
■
power supply.
The main board has an internal options connector which allows internal
options boards to access a variety of discrete and programmable signals.
For more information refer to
“Internal Options Connector” on page 43
.
For a basic block diagram of the main board, refer to
Figure 2.14 on
page 48
.
For a more detailed block diagram of the transceiver, refer to
Figure 2.16 on
page 53
.
Control-Head Board
The control-head board of the control head with graphical display includes:
■
the circuitry needed for the controls and indicators on the front panel
■
with a RISC processor and custom logic (implemented on an FPGA),
and memory.
For a block diagram of this control-head board, refer to
Figure 3.15 on
page 97
.
The control head with graphical display may have a concealed microphone
inside the control head and also has provision for a separate circuit board that
may be designed to perform a variety of tasks including—but not limited
to—Bluetooth connectivity. No separate circuit board is required for a
dynamic microphone.
