FIRST ACTIVITY: (100/100) . SIMPLE 4-BIT ARITHMETIC LOGIC UNIT (ALU): This circuit selects between arithmetic (absolute value, addition) and logical (XOR, AND) operations. Only one result (hexadecimal value) can be shown on the 7-segment display This is selected by the input sel (1..0) B A-BI A+B A xnor B A nand B Input EN: If EN-1result appears on the 7 segment display. If EN=0 → all LEDs in the 7 segment display are off Arithmetic operations: The 4-bit inputs A...

Consider 512Kx8bits dynamic RAM chips where the memory access time is 2/3 of the memory cycle time. These chips have an Address Bus, a bi-directional Data Bus, a Read/Write control line and a Chip Select line. (a) Draw the diagram of a memory organization that will contain 4 megabytes, will have a 32-bit bi-directional data bus and will yield one word (32-bits) every access time if words are read from consecutive memory locations (in bursts). Clearly show and explain the...

There is an example below
Now that everything is working you can try the following exercises. To complete them you will need to refer to the documentation in Appendix A The MiteASM Assembler and Appendix B The MiteFPGA Processor. Write an assembly language program for an over counter for a cricket umpire. This should 1. display a count on the 7-segment display. The count should increase by 1 when button 0 is pressed. It should reset to 0 when button...
can you explain the solution step by step?
I don't understand any..
3. [Memory Design] Build a 2K*16 bit ROM using any number of lK*8 bit ROMs The block you use to represent 2K* 16 ROM should have a 11-bit wide address input, a chip-select (CS) input, and a 8-bit wide data output. (Hint: A[9:0]: 10-bit address input, CS: a 1-bit chip-select input, Dout[7:0]: 8-bit data output.) 10 A[9:0] 1K X8 8 Dout 7:0 ROM CS 1 Ans: A19:0 49이...

Q4: Answer the following questions. [7 Marks] The single cycle implementation of MIPS is as shown below. Answer the following questions with reference to "beq $S1, $S2, 8H” instruction. Assume that the contents of the registers S1 = 10 H, S2 = 10H, and PC = 16H, pointing to the instruction under consideration. 1. What is the addressing mode of the instruction? [1] ii. Which part of the instruction format, address of S1 and S2 are stored? [1] 111. What...
Question 4: Single Cycle Datapath Control (15 points) We wish to add the hardware support for a special R-type instruction jlr Jump and Link Register) to the single-cycle datapath below. Though this is an R-type instruction, but it is a special one that has the opcode being 000001 (instead of 000000), so the control unit will be able to differentiate this jlr instruction from the other R-type instructions and generate a special set of controls for this instruction. Opcode rs...
1.) a.) Using the simplified instruction set shown for part b, write code for the following. Suppose memory locations 1400 to 1449 contain 16-bit words. Each word represents 2 ASCII characters. Write code to read in and write out these 100 characters. Left-side character from location 1400 should be first, right-side character from location 1400 should be second, and remaining characters follow in numeric order. Assume you have access to 4 registers: R1, R2, R3, R4. Each register holds one...
