New Embedded Systems Interview Questions :: ALLInterview.com http://www.allinterview.com New Embedded Systems Interview Questions en-us hi i want to learn embedded system course. can anyone tel me which tr http://www.allinterview.com/showanswers/100667.html What is mutex precisely used for? http://www.allinterview.com/showanswers/93344.html The mutex (mutually exclusion) variables are used thread synchroniization and for protecting the shared memory(data segment) when multiple writes occur wat are the different rtos available? wat is the difference beetween http://www.allinterview.com/showanswers/92156.html ordinary OS doesnt keep any time constraints n deadlines whereas RTOS,realtime OS keep time constrains for all processes that it keeps track of time consumed by each event n therefore maintains to finish tasks in specified time..RTOS are designed rtos kernal have memory managament,sheduler and timer but not haveing http://www.allinterview.com/showanswers/81857.html Where can i find the sample ASSEMBLY LANGUAGE programs????? plz tell http://www.allinterview.com/showanswers/76222.html write a c code. and generate the assembly for it using cc -S xyz.c -o xyz.S xyz.Swill contain assembly for your c code with instructions of the processor of your computer/hardware Is tasklets or workqueues or softirqs are scheduled by the scheduler? http://www.allinterview.com/showanswers/76019.html no whether the mulitasking and multiprocessing are same or not. http://www.allinterview.com/showanswers/74470.html NOT What is Difference between CAN and GMLAN http://www.allinterview.com/showanswers/68640.html CAN :- Implemented by boach GMLAN:- Implemented for GM for vehicle network an diagnostics What is the difference detween ISR & function call http://www.allinterview.com/showanswers/63620.html in isr there is no return value but in function call there is return value 7. What are tri-state devices and why they are essential in a bus or http://www.allinterview.com/showanswers/60960.html In a multiplexed bus system, many devices are connected to a common bus. If 2 or more devices attempt to use the bus at the same time , then data will be lost. Thus only one one device must be allowed to use the bus at a time. O e method is t can we create a table with out primary key? http://www.allinterview.com/showanswers/59851.html yes we can create.. what do you mean by embedded system? http://www.allinterview.com/showanswers/59406.html It's a combination of software and hardware Which are embedded by Kiel compiler.It 1s a device that do a specific task. write an assembly code which can call function in a loop with al valu http://www.allinterview.com/showanswers/35357.html xor ax, ax loop1: call foo inc al cmp ax, 10 jb loop1 Design a circuit to detect when 3 and only 3 bits are set out of 8 b http://www.allinterview.com/showanswers/20744.html Add the digits and check the sum. It would imply a 3-bit adder (max. value = 8 can be represented with three bits) and compare the result to 011. Design a circuit for A + abs(B) = C, where A and B are 4 bits wide a http://www.allinterview.com/showanswers/20743.html make a 4-bit adder/subtractor ( which can perform A+B and A- B depending on value of bit say SUB..ie if SUB is 1 it will perform A+B ) now give A and B as inputs and make MSB of B as SUB bit. suppose A=0110(6),B=1110(-2);so result will be A-B i
