Registers

The general-purpose registers, base registers, and index registers can all be used as the base in addressing modes, and all of those registers except for the stack pointer can be used as the index in addressing modes.

Given that the MMX's 64-bit MMn registers are aliased to the FPU stack and each of the floating point registers are 80 bits wide, the upper 16 bits of the floating point registers are unused in MMX.

Internal registers The CPU has eight 32-bit general-purpose data registers (D0-D7), and eight address registers (A0-A7).

Registers and instructions The 8086 has eight more or less general 16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers).

The base address from the table fulfills the same role that the literal value of the segment register fulfills in real mode; the segment registers have been converted from direct registers to indirect registers.

According to the secretary, majority of those who have visited their centres can neither find their names on the Voters Registers nor addresses, a situation which the party is blaming on the decision by the EC to combine the 2016 and 2019 registers.

He said most exhibition centres received only 2016 final registers without provisional registers of 2019, for example centres in Bongo Constituency, Bawku, Navrongo, Chiana and Paga etc.

A leading designer, builder, manufacturer, seller and exporter of cash registers in the 1950s until the 1970s was London -based (and later Brighton -based citation ) Gross Cash Registers Ltd., citation founded by brothers Sam and Henry Gross.

An odd-even number pair of double precision registers can be used as a quad precision register, thus allowing 8 quad precision registers.

Another technique involves spending silicon gates on "shadow registers": One or more duplicate registers used only by the interrupt software, perhaps supporting a dedicated stack.

A program that limits itself to eight registers per procedure can make very fast procedure calls : The call simply moves the window "down" by eight, to the set of eight registers used by that procedure, and the return moves the window back.

As supplied by DEC, it did not include paging hardware; memory management consisted of two sets of protection and relocation registers, called base and bounds registers.

Because it has larger registers than 3DNow!, SSE can pack twice the number of single precision floats into its registers.

Cash registers National Cash Register or NCR (Dayton Ohio) made cash registers around 1970 that would punch paper tape.

Each of them can be used as two single precision registers, providing a total of 32 single precision registers.

Each window has 8 local registers and shares 8 registers with each of the adjacent windows.

Hennessy felt that a careful compiler could find free registers without resorting to a hardware implementation, and that simply increasing the number of registers would not only make this simple, but increase the performance of all tasks.

In addition to the opcode, R-type instructions specify three registers, a shift amount field, and a function field; I-type instructions specify two registers and a 16-bit immediate value; J-type instructions follow the opcode with a 26-bit jump target.

In keeping with the "load/store" model of the PowerPC's RISC design, the vector registers, like the scalar registers, can only be loaded from and stored to memory.

In reality, they were implemented as a pair of 8-bit registers, citation in the same fashion as the HL register, which is accessible either as 16 bits or separately as the High and Low registers.
