Embodiment Construction

[0050] First, the data writing method of the present invention will be described with reference to FIG. 2.

[0051] Figure 2 shows a first or source storage area 21 containing source data 21'. The source storage area 21 is defined by a first or start position 21a and a second or end position 21b, which may contain zero, one or more intermediate positions 21c. Each start position 21a, end position 21b, and intermediate position 21c is an addressable position in the first or source addressable storage unit 31.

[0052] The storage unit 31 is a container that can hold data in a machine-readable format. The storage unit 31 may include one or more data storage devices, such as random access memory (RAM), read only memory (ROM), magnetic tape, magnetic disk, or magnetic drum. The storage component 31 is divided into volatile and non-volatile. It can be a main storage device, that is, the storage component 31 can be directly accessed by the computer central processing unit like RAM or RO...

Abstract

It is proposed a method for writing data in a system with alignment restriction, wherein first destination data (22') generated from first source data (21') located in a storage range (21) starting at a first source position (21a) are written in a storage range starting (22) at a non-aligned position (22a). Said method comprises the steps of extracting second source data (27') from a storage range (27) starting at a second source position (27)a preceding the first source position (21a), said second source data (27') comprising said first source data (21'), generating (23) second destination data (24') from said second source data (27'), said second destination data (24') comprising said first destination data (22'), writing said second destination data (24') in a storage range (24) starting at an aligned position (24a), wherein the second source position (24') is set such that said first destination data (22') are written in a storage range starting at said non-aligned position (22a).

Description

Technical field [0001] The present invention generally relates to the writing of data in a vector-based system, and more particularly to the writing of data in non-aligned positions of a vector-based writing system. Background technique [0002] In a system like memory that supports vector-based writing or storage, it is impossible to write data in any storage area of ​​the memory. In contrast, such a system is divided into a series of adjacent storage areas or vectors, and the system only allows data to be written in one or several complete vectors. In other words, data may only be written at a storage area starting at a so-called aligned position or address of the memory. These alignment positions are predetermined positions in the memory, and the process can start writing data at these predetermined positions. The storage positions between the aligned positions are called non-aligned positions. Data cannot be written to the storage portion starting from a non-aligned position....
