Patent Searching and Data


Title:
INTERLEAVE DEVICE
Document Type and Number:
Japanese Patent JPH05342097
Kind Code:
A
Abstract:

PURPOSE: To prevent operations from being delayed even when the non- coincidence of addresses is generated by providing a second storage means to store the data of a program without dividing them and to read the data only with a real address.

CONSTITUTION: Before the real address is outputted, a first-out address 8 is calculated by a microprocessor 7 and sent to a first storage means [ROM (A) 2 and ROM (B) 5.] A real address 9 is sent to a ROM 12 for second storage means miss recovery. The data of this the program due to this first-out address are read from first and second storage means 2, 5 and sent to a selector 13. On the other hand, data due to the real address are read from the ROM 12 for miss recovery and sent to a selector 13. The microprocessor 7 compares the sent first-out address with the real address and judges them and when those addresses are coincident, the read data of the first storage means 2 and 5 are selected. When they are not coincident, the read data of the second storage means 12 are selected by the selector 13.
