It is critical that more architectural registers are available to the compiler and programmer, as a small number of architectural registers might hinder the compiler and programmer from producing efficient code. Although modern chip manufacturing processes could easily put many registers on an ARM processor, only 16 general registers are accessible by the compiler and programmer. Doubling the number...
Conditional execution is an important ISA feature of the ARM series of processors. Every instruction can be made to execute conditionally, that is, it is treated as a NOP if the condition is not met. The advantage of conditional execution is that it can maintain high performance while reducing hardware complexity since it can avoid introducing pipeline bubbles even when no branch prediction units...
In this brief, we propose a lower error and ROM-free logarithmic converter. The proposed converter can lead to area-efficient hardware implementation as it avoids the need for a ROM by employing simple computation units for logarithmic approximation. Our proposed logarithmic conversion algorithm partitions the exact logarithmic curve into two symmetric regions such that the slopes in the two regions...
