摘要： A multiplication, division and square root extraction apparatus which calculates the solutions to addition, division and square root extraction functions by approximation using iteration has a multiplier, an adder-subtracter and a shifter of prescribed bit width connected to a bus. Iteration is conducted by inputting the output of the multiplier to the adder-subtracter or the shifter and returning the result to the input of the multiplier via the bus. A shifter and an arithmetic and logic unit connected to a second bus connected to the aforesaid bus via a switch have a greater bit width than the prescribed bit width and are used for large scale calculations, thus preventing a reduction in processing speed.

摘要： An address translation apparatus which includes a memory for storing a plurality of physical addresses, and a content addressable memory unit which stores a plurality of signal pairs that correspond to the plurality of physical addresses, each of the signal paris includes a logical address that corresponds to one of the plurality of physical addresses and memory protection level data that indicates a memory protection level allocated to a memory position of the one of the physical addresses. The content addressable memory unit includes apparatus for searching a signal pair that has a logical address in coincident with a logical address being subjected to address translation and comparing memory protection level data to comparative data at a bit position which is indicated to be the bit position to be searched by mask data, in response to the logical address translation. The mask data instructs whether the bits of the stored memory protection level data are to be searched, wherein mask data is determined depending upon a memory access privilege level allocated to a program that requests address translation, and whether comparative data are to be compared with the stored memory protection level data. The content addressable memory further includes apparatus for instructing the memory to produce a physical address that corresponds to the detected signal pair.
