Addressing 32,768 bytes of 6 bits would have been much less useful for scientific and engineering users. Or consider the 32-bit Pentium processor. Its 32-bit address bus can address 4 billion different items. Using word addressing, a 32-bit address bus could address 4 Gigawords; or 16 Gigabytes using the modern 8-bit byte. If we limit the address to four-byte boundaries, then the two least significant bits of the 32-bit address will always be zero (because the address will always be evenly divisible by four).

So your addresses are: 0x0, 0x4, 0x8, 0xC, etc My other recommendation is to include byteenables for your slave port. It is okay to have 4 byte alignment in the middle of a function, as long as the SP value is adjust back to 8 bytes aligned before the function is ended or a function call is made. If a function is coded in assembly language, and inside this function it calls another assembly function which you knew that it does not require 8 byte stack alignment, you can have 4 byte stack alignment at function call in such case. Byte is designed to work for minor to moderate alignment, including correcting spacing, crowding between teeth and rotation. Your at-home impressions will give us the information we need to know if you are a good candidate for byte.

A variable is naturally aligned if it exists at a memory address that is a multiple of its size.

Address byte alignment

Example: When having function calls, the SP value at function call boundaries should be 8 byte aligned. It is okay to have 4 byte alignment in the middle of a function, as long as the SP value is adjust back to 8 bytes aligned before the function is ended or a function call is made. Byte is designed to work for minor to moderate alignment, including correcting spacing, crowding between teeth and rotation.

Address byte alignment

__mm_load_si128 - the pointer address needs to be 16-byte aligned. From the ARM Neon instructions documentation, I was not able to find separate load / store   The rule mentioned above forms what we refer to as natural alignment: When accessing N bytes of memory, the base memory address must be evenly divisible by  12 Feb 2021 If an integer of 4 bytes is allocated on X address (X is multiple of 4), the processor needs only one memory cycle to read entire integer. Where as,  19 Jul 2020 Unaligned memory access is the access of data with a size of N number of bytes from an address that is not evenly divisible by the number of  Address bus that transfers the address request from CPU to the memory; Data bus that transfers the data bits (value) between CPU and the memory; Control bus  For this reason, it is worthwhile to check memory address alignment.

An access to an object Data alignment means that the address of a data can be evenly divisible by 1, 2, 4, or 8.

To understand whether the previous or the next even address is the "corresponding one", you must learn a bit about memory organization. Addressing 32,768 bytes of 6 bits would have been much less useful for scientific and engineering users. Or consider the 32-bit Pentium processor. Its 32-bit address bus can address 4 billion different items. Using word addressing, a 32-bit address bus could address 4 Gigawords; or 16 Gigabytes using the modern 8-bit byte.

Address (bytes) Alignment is a property of a memory address, expressed as the numeric address modulo a power of 2. For example, the address 0x0001103F modulo 4 is 3. That address is said to be aligned to 4n+3, where 4 indicates the chosen power of 2.
