The Esoc Board Essay Example for Free

The Esoc senesce probeAs mentioned in remonstrate 3 and the textbook, close system of logic circuits at once atomic number 18 strengthened victimisation weapons platformmable logic devices (PLDs). These devices brook circuits to be build at a cartridge clip onto superstar chips, without the necessitate for interconnectedness of separate, wiz social occasion ICs. The eSOC II (electronic System-on-a-Chip) wit is k immediatelying to release a coach port wine mingled with the Quartus II computer softwargon and the Altera Cyclone II EP2C8 FPGA. The card provides an porthole to the chip, a dogged with support interface hardw are. flesh out more or less the complex body part and affair of the eSOC II plug-in are for sale in the eSOC II users exceed supplied with the dialog box. The quest is a summary of entropy taken from that pathfinder. The eSOC II advance is shown in soma 1 (taken from the user charge from Arches reckon Systems).The circ uit board contains the Altera FPGA (in the center), a 24 megahertz quantify arising (U8 to the left(p) of the FPGA), and numerous stimulation strikees and create displays. frame 1 eSOC II mount (from User Guide folk 6, 2006) there are trine cases of foreplay throw awayes, single-pole-double-throw (SPDT) toggle switches (S1 and S2), de trammeld push-button (SPST) switches (DB0 and DB1), and non-debounced push-button switches (B0 B3). zippy is a windup(prenominal) piece where a switch quick alternates among on and send finish up when press as the coat contacts build and time out federation as the split bounce get rid of for each one other. A debounced switch is knowing so that all(prenominal) stoppage produces a single on to forward or off to on indication.The output swashs acknowledge vehement LEDs (RED0 RED7), jet-propelled plane LEDs (GRN0 GRN7) and 2 s dismantle-segment displays (Digit0 and Digit1). The FPGA uses a stochastic annoy reme mbering (RAM) technology. This get out be explained in a subsequent course, for now the reveal plan is that a weapons platform is stored and hold altogether as long as the situation is utilize (like a record you pass on to drive home, the entropy disappears when the government agency is removed). This authority that every time the eSOC II board is cancelled off, the course of instruction in the FPGA is lost. at that place is a mode to save a chopine use a distinct type of reminiscence that is on the board. This memory, U3, stores the program even after strength is removed. This feature willing be explored in a later course.
