Welcome to a tutorial on effective byte location. Effective Byte Location (EBL), also known as effective byte address, is a mapping of RAM addresses to bit-level addresses. In other words, EBL is a way to address memory at the level of individual bytes.

Let us take a look at an example to illustrate EBL in action. Assume we have a RAM (Random Access Memory) chip with 4 bytes of storage. These bytes are numbered from 0 to 3, as such:

Byte 0: 0101

Byte 1: 0011

Byte 2: 1000

Byte 3: 1111

Now, let’s assume we want to access the contents of Byte 2 from this RAM chip. To do so, we need to convert the RAM address of Byte 2 (2) to its effective byte location (EBL) address.

We can do this using the following formula:

EBL = 8 x RAM Address

Using this formula, we can calculate the EBL address of Byte 2 as 8 x 2 = 16. This means that in order to access Byte 2, we need to use the EBL address of 16.

In summary, Effective Byte Location (EBL) is a way to address memory at the level of individual bytes. The EBL of a certain RAM address can be calculated using the formula:

EBL = 8 x RAM Address
