The first аddress оf the memоry rаnge fоr the externаl SRAM is 0x108000. Below, specify the ending address for this memory range with a six-digit hexadecimal number that is prefixed with "0x" and does not include spaces, just as the starting address is given in the previous sentence immediately above. NOTE: You are expected to be able to solve this type of question without the use of a calculator or anything similar. You will not have access to such materials during the relevant lab quiz.
Tо identify hоw tо properly implement the hаrdwаre expаnsion, complete the schematic of Fig. 1 by matching some of the signal labels within the schematic to either [1] some other signal label(s) depicted within the schematic, [2] the label "VCC", [3] the label "GND", [4] some subset of the signal bus labeled "IN[7:0]", which is to denote the "inputs" of an 8-bit input port, [5] some subset of the signal bus labeled "OUT[7:0]", which is to denote the "outputs" of an 8-bit output port, or [6] the label "N/C", which is to denote that no connection should be made. For convenience, a PDF file of the below schematic is available here. NOTE: Some of the labels denoted in items [2]-[6] may not be needed. NOTE: In regard to item [1] , there are certain signals given within the below schematic that are meant to represent the enable equations that you should have defined for the previous question. Of course, the names of the Boolean equations that you defined may not match with the signal names presented below, but that is fine -- just recognize that this is where those enable signals come into play. (Hopefully the purpose of having the previous series of steps is now becoming clearer.) When actually building the relevant circuits within Quartus, it would be most appropriate not to utilize the meaningless naming convention presented below, but rather something similar to that which was defined previously (e.g., SRAM_CTRL for the SRAM control signal, IN_CTRL for the input control signal, OUT_CTRL for the output control signal, etc.). ———————————————————————————————————— For the purposes of this quiz question, consider only a single pull-up SPST switch circuit and a single active-high LED circuit. (However, for the relevant lab assignment, you must create eight of each.) Assume here that the single pull-up SPST switch drives the "least-significant bit" of the input port and that the "most-significant bit" of the output port drives the single active-high LED. In regard to the latch components given below, only utilize the one that is most representative of the latch device included on the OOTB Memory Base. (Study the relevant schematic, if necessary.) In regard to the tri-state buffer components given below, only utilize the one that is most representative of the 74HC573 8-bit 3-State Transparent Latch device, since this is the tri-state buffer device that will be used for the relevant lab assignment. In regard to the flip-flop components given below, only utilize the one that is most representative of the 74HC574 8-bit 3-State D Flip-Flop device, since this is the flip-flop device that will be used for the relevant lab assignment. Recall that address decoding must only be performed by external circuitry when a single chip select is not sufficient. For any extraneous circuitry depicted within the schematic, match all signals given for this circuitry to the label "N/C", and take this to mean that this circuitry is not utilized. Fig. 1. Hardware expansion schematic. ———————————————————————————————————— Within the matching pairs given below, signals associated with the microcontroller (e.g., "PK[7:0]", "PJ[7:0]", etc.) and signals "N[7:0]", "Q[7:0]", "Y", "AA", "AC", "AE", "AG", and "AI" are not listed on the left-hand side of any pair. This was done for several reasons, but the primary reason was that some of these signals may need to connect to multiple other signals, and Canvas does not offer any good way of having multiple matches for a single item. To circumvent this and other issues, these signals are given on the right-hand side of each matching pair, which successfully allows them to be matched with all other applicable signals, if any. Additionally, recognize that some of these signals are already utilized by circuitry depicted above, e.g., within the box labeled "PLD", signals "PH6", "PH4", "PH1", and "PH0", which come from the microcontroller, are each connected to at least one logic gate. Separately, in addition to single signal busses, note that some of the given matching options may represent any combination of [1] a concatenation of some signal busses (i.e., multiple signal busses grouped together into a single bus), [2] the result of some logical NOT operation, denoted with the forward slash (/) symbol, [3] the result of some logical AND operation, denoted with the asterisk (*) symbol, or [4] the result of some logical OR operation, denoted with the plus (+) symbol. For [1], the comma (,) symbol is used. More specifically, for any two signal busses S1[n1-1:0] and S2[n2-1:0], where S1 is an n1-bit binary number and S2 is an n2-bit binary number, "(S1, S2)" is an (n1+n2)-bit binary number, where the most-significant n1 bits represent S1 and the least-significant n2 bits represent S2. As an example, "(K[7:0], A[7:0])" would represent a bus of sixteen signals, where the most-significant eight signals are K[7:0] and the least-significant eight signals are A[7:0]. Lastly, in regard to [2], [3], and [4], you may assume that any resulting signal has the activation level that is most convenient for the above schematic. (Remember that the result of a Boolean operation, e.g., "F[7] * F[6] * F[5]" can be represented with either an active-high signal or an active-low signal, e.g., the example equation just given could be implemented with both an AND and NAND logic gate.) However, for all matching options below, there should only be one correct answer.
