    摘要: A digital signal processor capable of performing a Viterbi algorithm is provided. The digital signal processor includes an instruction fetching unit that fetches instructions; a decoding unit that decodes the instructions fetched by the instruction fetching unit, and an execution unit that executes the instructions decoded by the decoding unit. The execution unit includes a first comparing unit that compares first data with second data and a second comparing unit that compares third data with fourth data. The first comparing unit and the second comparing unit operate in parallel. Also, the first data, the second data, the third data, and the fourth data can each be one of four results obtained by adding one of two path metrics to one of two branch metrics. The execution unit outputs any two new path metrics in a high order position and a low order position respectively.

    摘要: An interleaving memory system having a first memory device including a 0-bank and a 1-bank for simultaneously outputting data at even-numbered addresses from the 0-bank and data at odd-numbered addresses from the 1-bank, a second memory device including a 0-bank and a 1-bank for simultaneously outputting data at even-numbered addresses from the 0-bank and data at odd-numbered addresses from the 1-bank, and a holding device for holding data from one of the banks of one of the first memory device and the second memory device to delay an output of the data for 1/2 cycle time for sequential addressing. A controller controls first and second selection devices wherein the 0-bank and the 1-bank are alternatively selected when data is outputted either in an ascending order of consecutive addresses from the even-numbered addresses in the first or second memory devices, or in a descending order of consecutive addresses from the odd-numbered addresses in the first or second memory devices. Also, the first holding device and a bank whose output is not held by the first holding device are alternatively selected when data is outputted either in a descending order of consecutive addresses from the even-numbered addresses in the first memory device, or in an ascending order of consecutive addresses from the odd-numbered addresses in the first memory device. The second holding device and a bank whose output is not held by the second holding device are similarly alternatively selected.
