Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale by providing an adding means, etc., which uses a cyclic redundancy check code (CRC), that is calculated by an operating means and newly replaces a CRC part on which information is rewritten among the original CRCs that is added to information before rewriting. SOLUTION: When old information is inputted, a latch 11 latches the inputted old information, addresses the latched old information and adds it to a RAM 12a. A 1st gate 13 compares the old information with new information, extracts bits whose values are different, and outputs them to a CRC operating part 2. Then, the part 2 performs 8 bit exclusive-OR processing for every string and acquires an operation result of CRCbit1 to CRCbit8. Also, the value of old CRC that passes through a delaying part 31 is applied to a 2nd gate 33 via a 1st selector 32. With this, the value of the old CRC is compensated in accordance with the operation result of the part 2, a CRC part is replaced with a new CRC value and it is outputted from a 2nd selector 34.

Title: Microcomputer
Inventor: TSUDA AKIYOSHI
IPC: G06F15/78
Filed: 1990-08-24
Abstract: PURPOSE:To omit the time required for a test not only by giving accesses in sequence to a RAM in the timing of the signal outputted from a timing generator but also by having an access to the RAM in the timing of an optional signal. CONSTITUTION:When a selection circuit 4 selects an output signal A produced from a timing generator 1, a data pointer 2 is decreased in the timing of the signal A. Therefore a RAM 3 also receives the accesses in sequence in the timing of the signal A. When the circuit 4 selects an optional signal D as an external input, the pointer 2 is decreased in the timing of the signal D. Thus the RAM 3 also receives the accesses in sequence in the timing of the signal D. As a result, the test time can be reduced.

Abstract: PURPOSE:To enhance the positional precision of a groove and an opening hole by a method wherein the wiring groove and the connecting opening hole connecting to the groove is formed on an insulating film and then the first conductive material is selectively buried in the connecting opening hole while the second conductive material is buried in the wiring groove. CONSTITUTION:An insulating film 2 is deposited on a basic consti tuent element containing an n<+> diffused region 11 of an Si substrate and then a wiring groove 3 and a connecting opening hole 4 connecting to the groove 3 are formed by pattern formation and etching process of resist layers 71, 72. Next, the first conductive material 5 is selectively buried in the opening hole 4 and then the second conductive material 6 is buried in the groove 3 however any needless part is removed since the material 6 is formed on the whole surface due to the lack of selectivity. Through these procedures, the opening hole 4 can be formed with excellent positional precision thereby enabling the effective contact space to be widened as well as the conductive materials to be easily processed.
