NettetThe Pentium 4 and Intel Xeon processors implement the PAUSE instruction as a delay. The delay is finite and can be zero for some processors. This instruction does not change the architectural state of the processor (that is, it … Nettet6. aug. 2024 · Addressing in x86-64 can be relative to the current instruction pointer value. This is indicated with the RIP (64-bit) and EIP (32-bit) instruction pointer registers, which are not otherwise exposed to the program and may not exist physically. RIP-relative addressing allows object files to be location independent. de in the nfc https://phillybassdent.com

Transactional Synchronization Extensions (TSX), also called Transactional Synchronization Extensions New Instructions (TSX-NI), is an extension to the x86 instruction set architecture (ISA) that adds hardware transactional memory support, speeding up execution of multi-threaded software through lock elision. According to different benchmarks, TSX/TSX-NI can provide around 40% faster applications execution in specific workloads, and 4–5 times more database transacti… Nettetfor 1 dag siden · A note on this.

NettetA lock can be built using an atomic test-and-set [1] instruction as follows: This code assumes that the memory location was initialized to 0 at some point prior to the first test-and-set. The calling process obtains the lock if the old value was 0, otherwise the while-loop spins waiting to acquire the lock. This is called a spinlock. NettetBelow is the full 8086/8088 instruction set of Intel (81 instructions total). Most if not all of these instructions are available in 32-bit mode; they just operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.The updated instruction set is also grouped according to architecture (i386, i486, i686) and more …

NettetThe LOCK # signal is asserted during execution of the instruction following the lockprefix. This signal can be used in a multiprocessor system to ensure exclusive use of shared memory while LOCK # is asserted. The btsinstruction is the read-modify-write sequence used to implement test-and-run. http://ref.x86asm.net/
