The addressable memory space of a microcontroller or microprocessor depends on their address bus width. For instance, if we take the example of ARM Cortex M4 32-bit microcontroller, its addressable memory space is 2^32 which is equal to 4 gigabytes of memory. Each byte of this memory space ...
The single event effects of the sensitivity of a circuit are investigated on a 32-bit microprocessor with a five-stage instruction pipeline by pulsed laser test. The investigation on sensitive mapping of the memory cell is illustrated and then the comparison between the sensitive mapping and the ...
The difference between the two schemes occurs within the microprocessor. Intel has, for the most part, used the port mapped scheme for their microprocessors and Motorola has used the memory mapped scheme. As 16-bit processors have become obsolete and replaced with 32-bit and 64-bit in general ...
A device's direct memory access (DMA) is not affected by those CPU-to-device communication methods, especially it is not affected by memory mapping. This is because, by definition, DMA is a memory-to-device communication method, that bypasses the CPU. Hardware interrupt is yet another communi...

Given a fixed number of bits in the cache, we can vary both the set associativity and the line size. Splitting a cache into more sets allows us to independently reference more locations that map onto similar cache locations at the cost of mapping more memory addresses into a given cache ...
In addition, the memory blocks are mapped in the topology by taking advantage of spatial locality, i.e. mapping memory blocks to physical locations on the chip that are close to the cores that access them, while reducing the access conflicts. Communication locality reduces the average distance ...

We also retested the gal4 driver, elavc155-gal4, in this spatial and cell-type mapping study. The gal4-driven expression of miR-31a-SP (in the attP40 site) had no effect on 3-hr memory compared to the associated scrambled control in any specific neuronal population tested except for ...
