1. Electronic technology terminology

DS (Digital signal) refers to a signal in which the independent variable is discrete and the dependent variable is also discrete. The independent variable of this signal is represented by an integer. , the dependent variable is represented by a number among a finite number.

2. Digital signature

DS is a digital signature and one of the most important concepts in the development of public key cryptography. It can provide security that is difficult to achieve by other methods. It is similar to traditional A handwritten signature is similar.

3. Assembly language terminology

DS in assembly language means data segment register (Data Segment register). The segment register DS points to the data segment and ES points to the additional segment. When fetching the operand, combine one of the two with an offset to get the physical address of the storage unit.

Introduction

In computer architecture, the register in the processor is a small and fast computer memory that speeds up the computer by providing fast and co-located access to values. The execution of a program: typically the calculation of intermediate values ??at known points in time.

The scratchpad is the top of the memory hierarchy and the fastest way for the system to manipulate data. Registers are usually measured by the number of bits they can hold, for example, an 8-bit register or a 32-bit register.

Scratchpads are currently implemented as scratchpad arrays, but they may also use separate flip-flops, high-speed core memory, thin film memory, and other means on several machines. Realize it.
