What is the different between LXI and LHLD in 8085?LHLD 2050 Means..copy content of 2050 and 2051 to HL pairif2050 -> 90H2051->5AHLHLD 2050 implies..L -> 90HH -> 5AHLXI means..Load Register Pair with Immediate data.. 16bit dataLXI B ,2050HLoads BC pair with value 2050HB-> 20HC-> 50HIts similar to 2 MVI instructionieMVI H,20HMVI L,50Hwhich eventually implies..HL -> 2050Hthe advantage of LXI over MVI is that LXI is 3 byte and requires 10T states.Two MVI instruction is 4Byte and require 14Tstates...
RST 5.5 is an interrupt request pin (pin 9) on the 8085. It is sampled, along with other interrupt requests, one clock cycle before ALE on the falling edge of CLK. When enabled, and having priority, it causes an interrupt vector sequence using the RST 5.5 instruction, going to location 002CH.
there is an a

program to find prime number in 8085 microprocessor
in 8085 only one accumulator used where in 6800 used two accumulator.
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
The most significant difference between the Intel 8085 and 8086 microprocessors is that the 8085 is an 8-bit system and the 8086 is a 16-bit system. This difference allows the 8086 system to have a much larger set of operational instructions and can make calculations to more significant places. Note: the 8085 processor does have two 16-bit registers. The pointer and the program counter.
8085 is a microprocessor designed by Intel
The Intel 8085 is an 8 bit microprocessor created in 1977.The Intel 8086 is a 16 bit microprocessor created in 1978. The 8086 was the first chip to start the x86 architecture family.8085 contains 16-bit address bus and 8-bit data bus8086 contains 20-bit address bus and 16-bit data bus..In 8085 the clock speed is 3MHZwhere as in 8086 the clock speed is 5MHZ.there are two differences btw 8085&80861. 8086 has 6 byte queue but 8085 has 4 byte queue2. 8086 has 16 bit data bus where as 8085 has 8 bit data bus
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
The width of the address bus on the 8085 was decided based on a compromise between functionality, cost, and complexity. Intel decide to use 16 bits, as that was in keeping with common design at that time, and also because the 8085 was actually an enhanced version of the 8080.
The 8085 was introduced by Intel in 1977.
