Ecc read modify write
WebSmaller write accesses (32-bit/16-bit/8-bit) cause the read-modify-write operation with ECC error-affected data. # Store number of 128Byte (32GPRs) segments in Counter e_lis r5, _SRAM_SIZE@h # Initialize r5 to size of SRAM (Bytes) ... All application read or write accesses to these registers are delayed until the initialization is finished. Web• Faster Atomic Operations —users requested faster read-modify-write atomic operations for their parallel algorithms. With these requests in mind, the Fermi team designed a processor that greatly increases raw compute horsepower, and through architectural innovations, also offers dramatically increased programmability and compute efficiency.

WebRead–modify–write. In computer science, read–modify–write is a class of atomic operations (such as test-and-set, fetch-and-add, and compare-and-swap) that both read a memory location and write a new value into it simultaneously, either with a completely new value or some function of the previous value. These operations prevent race ...
