How many machine cycles are there in 8085?
How many machine cycles does 8085 have, mention them? In 8085 have 9 machine cycles, they are opcode fetch, memory read, memory write, I/O read, I/O write,Interrupt acknowledge, halt, hold & reset.
How do you calculate number of machine cycles?
In the 8051, one machine cycle lasts 12 oscillator periods. So to calculate the machine cycle, we take 1/12 of the crystal frequency, then take the inverse of it results in time period. i.e frequency = 1/time period.
What is the time taken by one machine cycle if crystal frequency is 20 MHz?
What is the time taken by one machine cycle if crystal frequency is 20MHz? Explanation: It will be executed 200*100 times.
How many rows and columns are present in a 16 * 2 alphanumeric LCD?
How many rows and columns are present in a 16*2 alphanumeric LCD? Solution: 16*2 alphanumeric LCD has 2 rows and 16 columns.
What is ANL in 8051?
The ANL instruction performs a bitwise logical AND operation between the specified byte or bit operands and stores the result in the destination operand. Note. When this instruction is used to modify an output port, the value used as the port data will be read from the output data latch, not the input pins of the port.

Which are the processor based on RISC?
Which are the processors based on RISC? Explanation: SPARC and MIPS processors are the first generation processors of RISC architecture. 2.
Is RISC architecture still used?
Yes, ARM is a RISC architecture, and is the most used in the world. As I understand it, these days CISC and RISC isn’t the big divide it used to be. RISC architectures get CISC-style features, and vice versa. Sure, a few of the most powerful supercomputers on earth are RISC.
Is MIPS CISC or RISC?
MIPS is RISC (Reduced Instruction Set Chip) architecture. Reduced (RISC) architectures tend to be simpler and have a small number of operations. Complex (CISC) architectures like x86 have more instructions, some of which take the place of a sequence of RISC instructions.
Is MIPS a RISC-V?
“MIPS is developing a new industry-leading standards-based 8th generation architecture, which will be based on the open-source RISC-V processor standard.”
How do you calculate MIPS rate?
- Divide the number of instructions by the execution time.
- Divide this number by 1 million to find the millions of instructions per second.
- Alternatively, divide the number of cycles per second (CPU) by the number of cycles per instruction (CPI) and then divide by 1 million to find the MIPS.
Is MIPS processor a RISC?
MIPS (Microprocessor without Interlocked Pipelined Stages) is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by MIPS Computer Systems, now MIPS Technologies, based in the United States. …
What is the difference between RISC and RISC-V?
RISC-V is an open standard instruction set architecture that uses RISC principles of basic, fewer instructions than compared to CISC. While this makes RISC-V slower than CISC, it allows RISC-V to be simpler in hardware design, and therefore uses less silicon space.
Does anyone use MIPS?
Answering your second question: yes, MIPS processors are still in use. They’re frequently the processors used in things like routers and other small computing appliances like that. They’re also increasingly appearing in small home computing devices in Asian marketplaces (Lemote, for example).
