摘要： The present invention contemplates an improved multiplier circuit and method for reducing power consumption by reducing the number of transitions to the input of the multiplier. Each input to the multiplier is fixed for as long as possible by reordering the sequence of the multiplications to take advantage of duplicate input values. The intermediate results of each multiplication are stored in separate accumulators to obtain the final resultants. Power consumption is further reduced through a reduction in the number of transitions on the data bus linking the multiplier and the data register file containing the accumulators.
摘要翻译：本发明考虑了改进的乘法器电路和方法，用于通过减少向乘法器的输入的转换次数来降低功耗。通过重新排序乘法序列以利用重复输入值，乘法器的每个输入被固定为尽可能长的时间。每个乘法的中间结果存储在单独的累加器中以获得最终的结果。通过减少连接乘法器和包含累加器的数据寄存器文件的数据总线上的转换次数，能够进一步降低功耗。

摘要： A memory system including a first memory area (MEM-A) implemented using memory units including low threshold voltage transistors powered by a low supply voltage source, and a second memory area (MEM-B) implemented using memory units including higher threshold voltage cells powered by a higher supply voltage source. The first memory area, MEM-A, is designated to contain frequently accessed variables, with less frequently accessed variables designated for storage in the second memory area, MEM-B. The most frequently accessed variables stored in MEM-A provide for fast access at a low power per access power dissipation level due to the lower supply voltage and lower threshold voltage design. Alternatively, the less frequently accessed variables stored in MEM-B require a high power per access, but negligible leakage current during static steady state conditions.

摘要： Providing a wireless communication device that, even if clock stop of a radio frequency part is controlled by a baseband part operating on the same clock signal, can resume clock oscillation, and makes it easy to time the clock reactivation to other operations based on a shared clock. The wireless communication device comprises an RF part generating a first clock signal and a baseband part. The baseband part generates a second clock signal, controls the generation and stop of the first clock signal, uses the first clock signal to perform data processing and a clocking operation, and in a low power consumption state in which the first clock signal is stopped, uses the second clock signal to perform a timer operation and a clocking operation. The generation timing of the first clock signal can be generated by the timer operation using the second clock signal.
