index register उदाहरण वाक्य
उदाहरण वाक्य
- The first three bits of an operand address could designate one of six index registers that occupied the first 32 addressable memory locations.
- Thus, register X1 is being used as the index register, and the offset, v, is specified in the second byte of the instruction.
- There was also a program counter, four index registers, and a 16-bit real time clock register which was incremented 32 times a second.
- When indexing is specified, the register defined in the instruction becomes the index register, and the source / destination is implicitly Register zero.
- Typical instructions contain a function code, the target ( or source ) register, an index register, a base register and a displacement field.
- Additionally, a third index register ( Z ) was included, the stack pointer was widened to 16 bits, and the direct page addressing mode.
- Additionally, several commands that used the index registers had side effects that led to quirky programming, but these were modified to have no side effects.
- In most ISRs, the accumulator and / or index registers must be preserved to assure transparency and later restored as the final steps prior to executing.
- An instruction word consisted of 11 bits for an address, two bits for index register selection, and 7 bits for the operation code and its modifiers.
- There were no index registers, and as addresses were stored in the instructions, loops had to be implemented by modifying the instructions as the program ran.
