Enhanced memory addressing capability
If an address consists of 8 bits, the addressing capability or the largest number of cells which can be uniquely selected is 28 = 256. This range is called the address space of the computer, and it does not need to have actual memory cells for all of these locations. A small computer ...
ECC is the error correction capability provided by the CPU, and DRAM-specific failure characteristics depend on the microarchitecture of the DRAM. Furthermore, not all faults or pages within a certain rate of CEs are equally likely experience future UEs. The rate CEs in the past is not a ...
DMA offers a high performance capability to DSPs. Modern DSP DMA controllers such as the TMS320C6x can transfer data at up to 800 Mbytes/sec (sustained). This DMA controller can read and write one 32-bit word every cycle. Offloading the work of transferring data allows the CPU to focus...
This capability is partic- ularly useful when writing data fetched after a miss into the cache or when writing back a block that must be evicted from the cache. The access time to the cache (ignoring the hit detection and selection in a set associative cache) is proportional to the number...
As indicated by the physical address word shown on line 3, each sub-memory 313 has an addressing capability of 128K words (K=1024) and memory 311 has a maximum capacity, with eight sub-memory 313's, of one megaword. As shown on line 4, however, direct physical addressing (address bits...

Moreover, to assess the capability of computational mem- ory to compete with already existing low-precision CMOS- based accelerators for performing matrix-vector multiplica- tions, we designed a low-precision 4-bit matrix-vector mul- tiplier on a field-programmable gate array (FPGA) with an ...
temporary storage area which holds the data and instructions that the CPU needs) to execute all programs. Thus, the more programs memory holds, the less free space memory has. Therefore, Windows operating systems like adopting the virtual memory technology to increase computer’s memory capability....
