Improving software and application development capabilities and providing
efficient code debug competence are among CEVA's top priorities. This
is demonstrated by the newly released JTAG interface, named JBox. The
JBox enables operation of all CEVA DSP cores in debug emulation mode.
It provides a bridge between the PC host and the target board, and it
allows JTAG high-speed communication with the DSP subsystem for software
development and debug.
The JBox uses a standard 4-signal JTAG connection to communicate with
the target DSP platform. It communicates with a PC via standard parallel-port
(EPP/SPP modes) or via a USB-port interface for CEVA-Teak and CEVA-TeakLite
DSSP cores.
The JBox can be driven by either a standard power supply, or the USB
cable. The JBox also supports general-purpose connectors to allow direct
reset and any other general-purpose signal generated by the PC host.
- PC Parallel-Port (EPP/SPP modes) or USB (soon to be implemented)
connections for communication with PC applications
- JTAG connector to interface the chip on any platform
- External 5V-6V AC/DC standard power-supply
