Title: Decimal arithmetic circuit
Inventor: MORI SHIGEMI
IPC: G06F7/494
Filed: 1991-09-10
Abstract: PURPOSE:To increase the speed of a decimal arithmetic instruction by performing automatically the pre-matching of digits of the decimal arithmetic data, the decimal computing operation, and the transformation of the computing result into eight bits within a decimal arithmetic circuit. CONSTITUTION:When the computed data on a decimal arithmetic instruction is not matched with the lowest order digit position of the computing data, the computed data outputted from a selector 1 are inputted as they are to the decimal ALU (arithmetic logic computing part) 4 and 5. However the computing data outputted from a selector 2 are switched between the higher and lower order digits and then inputted to the ALU 4 and 5. If the valid digit of the computed data is set in a lower order, the ALU 5 performs the decimal arithmetic and holds this computing result in a register 6. If the valid digit of the computed data is set in a higher order, the ALU 5 just transmits a carry 38 and the ALU 4 carries out the decimal arithmetic. Then the outputs of the ALU 4 and 6 are added together and outputted as the 8-bit computing result.

Title: Magnetic recorder
Inventor: IMAI YUTAKA
IPC: G11B20/10
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To detect a target data sector and to read out it by performing forced read when it isn't dissolved even though repeating retry of regular read. SOLUTION: When the data sector isn't detected while processing read, a CPU 9 instructs an HDC 12 on read retry to retry prescribed times. When normal read is impossible even that, the forced read is performed. At this time, the CPU 9 obtains the number of counts until the target data sector from a reference servo address and its address by referring to a table of a ROM 10 and operation processing, and sets it in a pulse generation circuit and a timer in the HDC 12. The HDC 12 counts the number set in a counter based on an F-INDEX outputted from the circuit 6, and instructs a read/write circuit 8 on read at the point of time of the target data sector to perform the forced read. When it succeeds, automatically alternate processing is performed, and since the data in the forcedly read data sector are stored, the forced read at the next read time of the data is eliminated.
