Title: Memory access circuit
Inventor: TOKUCHI HIDEAKI
IPC: G06F12/04
Filed: 1988-09-13
Abstract: PURPOSE:To effectively use the capacity of a memory by multiplexing an address from a CPU by a means which reads word data out of an 8Xn-bit CPU within one bus cycle. CONSTITUTION:This circuit is equipped with an address conversion part 10 which adds '1' or 'n-1' to the address value of address information from a CPU part 7 to generate new address information and makes access to a memory with this new address information at the time of word access to an even- numbered address and a low-order data latch part 12 which latches low-order data read out of the memory by the word access to the even-numbered address. Then when word access to an odd-numbered address, byte access to an even- numbered address or byte access to an odd-numbered address is carried out, the CPU read 8Xn-bit data in parallel within one bus cycle without the generation of multiple access nor the latching of low-order data. Consequently, the capacity of the memory can be used effectively.

IPC: G01B7/00
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To improve measurement precision of angle of rotation by keeping good linearity between rotation angle and measurement value of magnetic flux density ion wide of angle or rotation range. SOLUTION: A sleeve 2 concentric with a rotation axis 1 is fixed to a fixing side. The rotation axis 1 goes through inside the sleeve 2 and a Hall element 3 which measures magnetic flux density is attached on the outside of the sleeve 2.
