摘要： A method for decoding multiword information comprises steps (a) to (e). In step (a), a multiword information cluster, e.g., ECC, including high protective codewords, e.g., BIS, and low protective codewords, e.g., LDC, is provided. In step (b), the high and low protective codewords are stored into a first memory, e.g., DRAM. In step (c), the high protective codewords are decoded to generate high protective word erasure indicators showing whether decoding errors occur. In step (d), the high protective word erasure indicators are stored into a second memory, e.g., SRAM. In step (e), the low protective codewords are decoded. In the meanwhile, an erasure bit for a low protective codeword is marked by finding high protective codewords close to the low protective codeword in the multiword information cluster and looking up the high protective word erasure indicators of the high protective codewords close to the low protective codeword.

摘要： An apparatus for branch detecting a loop operation in a microprocessor. The apparatus includes a register, an ALU port, a predetector, an ALU, a flag generator and a branch detector. The register is provided for storing a loop information. Through the ALU port, the loop information is sent to the predetector and is predetected therein whenever the loop operation is about to proceed. A predetected result is then generated by the predetected and is sent to the branch detector to determine whether the loop operation has to be terminated. The ALU processes the loop information and updates new loop the register at the same time the predetection and detection tasks are performed by the predetector and the branch detector, respectively. The flag generator generates a flag which is independent of the detection and termination of the loop operation.

During the encoding operation, the number of the data access of the dynamic random access memory (DRAM) with the row address switching can be reduced considerably via using the additional SRAM or multi-symbol encoder. Hence, the efficiency of the data access of the DRAM is improved and the encoding time of the error correction code generator is reduced.
