1. Module ID The module has an ID hard wired to 1 That is the signals MID 1 3 are grounded and the signal MIDO is driven by 3 3V Carrier ID The carrier ID will generally not be relevant in a system with a HERON BASBE1 so the signals CID 0 3 are pulled to ground with a 10K resistor Each of them is tracked to a jumper which has the other side connected to 3 3V allowing different carrier IDs to be set using simple jumpers Each of the jumper fields is labelled with the bit number For example the picture shows a link fitted to field 1 meaning that the value is binary 0010 i e Carrier ID 15 2 Reset There is a Max705 chip used to provide a 200ms power on reset which also offers the possibility of using a reset button to provide a 200ms reset The pin that is connected to this is connected to the I Os connector allowing a simple switch to be connected there if an external reset is required A logical 0 signal could also be used as an input here to externally cause a reset The reset signal from the MAX705 is buffered through an LVT245 so that a 3 3v signal is connected to the module A separately buffered version of this reset is used to light an LED when the reset is asserted Address Flagsel This signal can be used by modules to select if certain pins of the HERON module are used 8 HUNT ENGINEERING HERON BASEI USER MANUAL as address lines or FIFO flags The pins are actually not used at all on a HERON BASE12. eee ee nsns 11 FITTING MODULES TO YOUR CARRIER 12 TROUBLESHOOTING 5 2 2 2 co eoo nno annoa aD necp I re co ee ea Dos nocere n Das er Ge 13 HARDWARE 13 EBGAMODU LBS 13 DSP2AMODUEDES 13 CE MARKING sessdeuecsensslbeccceocceseteteles 14 TECHNICAL SUPPOR ED 15 3 HUNT ENGINEERING HERON BASEI USER MANUAL Introduction The HERON module is a module defined by HUNT ENGINEERING to address the needs of our customers for real time DSP systems The HERON module is defined both mechanically and electrically by a separate HERON module specification that is available from the HUNT ENGINEERING CD via the user manual section from the CD browser or online from http www hunteng co uk and going to the application note section under the user area The HERON module specification also defines the features that a HERON module carrier must provide HERON stands for Hunt Engineering ResOurce Node which tries to make it clear that the module is not for a particular processor or I O task but is intended to be a module definition that allows nodes in a system to be interconnected and controlled whatever their function In this respect it is not like the TIM 40 specification which was specific to the C4x DSP As the HERON BASE1 was developed HUNT EN

7. GINEERING have already developed HERON modules carriers like the HEPC8 HERON processor modules that carry various other members of the TMS320C6000 family of DSP processors from TI and HERON FPGA and HERON IO modules with Xilinx FPGAs The HERON module is able to connect to the carrier board through several standard interfaces first is a FIFO input interface and a FIFO output interface This is to be used for the main inter node communications It is usually also used for connection to the HOST computer if any e The second is an asynchronous interface that allows registers etc to be configured from a HERON module This is intended for configuring communication systems or perhaps to control some function specific peripherals on the carrier board The third is a JTAG IEEE 1149 1 interface for running processor debug tools e The Fourth is the HERON Serial Bus used for configuration messages The last is the general control such as reset power etc HUNT ENGINEERING defined the HERON modules in conjunction with HEART the Hunt Engineering Architecture using Ring Technology This is a common architecture that we will adopt for our HERON carriers that provides good real time features such as low latency and high bandwidth along with software reconfigurability of the communication system multicast multiple board support etc etc However it is not a requirement of a HERON module carrier that it implements such f

9. T ENGINEERING HERON BASEI USER MANUAL Getting Started The HERON BASE1 is a stand alone module carrier so all you need to do is fit the module that you will use and apply power Note that just like the HERON module there are 5V 12V and 12V power supply connections to the HERON BASE1 You need only connect the power supplies that are needed for the module you ate using As an example if you are using the HERON IO2 you do not need to connect 12V as the module does not need it All power supplies have LEDs to show when they are active so only the LEDs for the supplies connected should be alight The HERON BASE1 generates a 3 3V supply for use in driving some of the signals to the HERON module slot This LED should always be lit The HERON BASE1 is designed to provide a reset to the HERON module when the 5V supply is switched on A reset can be forced by joining two pins on the I Os connector This input is de bounced so a simple reset switch can be connected that simply joins the reset input to the adjacent ground pin 7 HUNT ENGINEERING HERON BASEI USER MANUAL Board Features This section describes the features of the HERON BASE1 and why they are provided FIFO clocks The FIFO clocks of the module slot are terminated as required by the HERON specification This should not be necessary as the FIFO interface is not used but doing so reduces the risk of system noise being introduced by these clocks being unterminated
