What is exhaustive decoding?
Exhaustive Decoding: When all the address lines of the processor are used to specify the address of a memory location, exhaustive decoding is said to be used
Outline steps in CPU writing to memory?
1 The processor puts the required addresses on to the address bus 2 Any addresses that invoke chip select are decoded 3 Chip select is generated 4 The processor waits for memory to settle 5 The processor generates a memory write control bit (MEMW) 6 The processor puts the data on to the data bus 7 The contents are written to a specific location on memory.
What is the function of the WR signal on the memory chip?
what is the function of the wr signal on memory chip
What is the differencebetween on-chip and off-chip memory?
On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
What is decoding on Club Penguin?
On some Club Penguin missions, there is a code that needs to be decoded. There is a key to the code, so you can just decode it to find out what it says.
What are real life applications of encoder and decoder?
Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.
What memory is readable but not writeable in a chip computer?
BIOS chip
Is a chip permanent memory?
no
What happens during the fetch phase of the MPU cycle?
the opcode is fetched from the memory and decoded
How many register in 2K memory chip?
Registers represent the number of memory locations. A 2K memory chip has 2x1024=2048 memory locations. Hence there are 2048 registers in a 2K memory.
What role does the CPU Instruction Register IR play in the decoding of machine instructions?
The IR is a register constisting of two parts, opcode and address. The opcode is decoded and gives instructions to the control unit whilst the address part is used to give the location in the memory of for example data required for a certain process
Where do i get a iPhone memory chip?
There's no such thing. The iphone does not have a memory chip you can plug in. If you mean internal spare parts then ebay.
