How do you draw the timing diagram for instruction INX H?
INX H instruction requires 1 machine cycle having 6 T-states because 8-bit instruction operate on 16 bit data (HL) completed in 6 T-states.
What address in the bit band region of the cortex m3 contains the bit that correspond to word address 2201234 in the bit band alias?
In the Cortex-M3 architecture, the bit band region allows for individual bits of a word in memory to be accessed directly. To find the corresponding bit in the bit band alias for a word address of 2201234, you can use the formula: Bit Band Address = (Bit Band Base) + (Word Address * 32) + (Bit Number). The bit band base for SRAM is typically 0x20000000, so the corresponding bit address would be calculated accordingly. For the given word address, you would first convert it to the bit band address by substituting the values into the formula.
Difference between two address instruction and one address instruction?
Two address instructions use registers as operand locations.Example of a half word length (16 bit) Two address format.Bits 0-3 OP-Code bits (4 bits 16 different Mnemonics).Bit 4 instruction type ( e.g. 0 means half word length).Bit 5 fixed at value 1 used as extension to op-codes.Bits 6-9 Address A (4 bits refers to a registers hence a total of 16 registers).Bits 10-11 addressing modes ( 2 bits hence 4 different addressing modes in this case).Bits 12-15 Address B (4 bits refers to a registers hence a total of 16 registers).If 16 OP-codes for One address instructions is to be: ADD, ADC, SUB, SBC, XOR, BIT, CMP, INC, DEC, LDA, STA, AND, OR, JMP, BRN, JSR.For Two address instructions the following 6 OP-Codes are dropped: INC, DEC, STA, BRN, JMP, JSR, but new OP-Codes with the help of bit #5 is introduced instead------------------------------------------------now let's to introducingOne Address InstructionsThis is for a 32 bit CPU word length.Bits 0-3 OP Code bits (4 bits 16 different OP Codes).Bit 4 word length (0/1 Two different length 16 or 32 bit in this case).Bits 5-7 Addressing Modes (3 bits 8 different Addressing Modes).Bits 8-31 # of Addresses (2^24 Addressing Options).The possible OP-Codes could be: ADD, SUB, ADC, SBC, AND, XOR, ORA, BIT, CMP, LDA, STA, INC, DEC, BRN, JSR, JMP.one addressing24 bit Address3 bit AM1/0OP Codetwo addressing0000001111100010
How do you draw a basic logic diagram for a 512x8 bit static RAM?
To draw a basic logic diagram for a 512x8 bit static RAM, start by creating an address decoder that takes a 9-bit input (since (2^9 = 512)) to select one of the 512 memory locations. Each memory location will have 8 output lines for the 8 bits of data, which can be represented as a set of 8 D flip-flops or memory cells. Connect the address lines to the decoder's inputs, and wire the selected output to the corresponding memory cells. Additionally, include control signals for reading and writing data to complete the diagram.

How many Terabytes of memory would a 40 bit address bus be able to address if the system word length was 8bits 16bits 32bits?
1TB is 240 bytes. It follows that a 40 bit address bus can address 1TB. Since 1TB is 1TB regardless of the system's word size, a 40 bit address bus can address 1TB on a computer with an 8 bit, a 16 bit, a 32 bit, or any other word size.
How are segment registers used to form a 20-bit address?
The 16 bit segment register is left shifted by 4 and added to the effective address to form a 20 bit physical address.
What is higher order address of a 16 bit address?
In the 8085, the high order address is A8-A15. In the 8086/8088, the high order address is A8-A19. (For a 16-bit address, the answer is A8-A15, but the answer above reflects the chosen categories, 8085 and 8086/8088, with the 8086/8088 running in 20-bit mode.) In Windows XP, running in 32-bit mode, the high order address is A8-A31, a 32 bit address.
Address bus width?
Varies from machine to machine:many early machines had address busses only 12 to 18 bits wideearly microprocessors has address busses 10 to 14 bits wide16 bit address busses were common on microprocessors in the early 1980sthe 8086 had a 20 bit address bus and the 68000 a 24 bit address busmost modern computers have 32 bit address busses with high-end ones having as many as 64 bit address busses
