20140281373 | DIGITAL SIGNAL PROCESSOR AND BASEBAND COMMUNICATION DEVICE - A digital signal processor has a vector execution unit arranged to execute instructions on multiple data in the form of a vector, comprising a local queue arranged to receive instructions from a program memory and to hold them in the local queue until a predefined condition is fulfilled. The local queue being arranged to receive a sequence of instructions at a time from the program memory and to store the last N instructions, N being an integer. A vector controller in the vector execution unit comprises queue control means arranged to make the local queue repeat a sequence of M instructions stored in the local queue, M being an integer less than or equal to N, a number K of times. This reduces the time the vector execution unit is kept waiting because of IDLE commands in the program memory. | 09-18-2014 |
20140244970 | DIGITAL SIGNAL PROCESSOR AND BASEBAND COMMUNICATION DEVICE - For increased efficiency, a digital signal processor comprises a vector execution unit arranged to execute instructions that are to be performed on multiple data in the form of a vector, comprising a vector controller arranged to determine if an instruction is a vector instruction and, if it is, inform a count register arranged to hold the vector length, said vector controller being further arranged receive an issue signal and control the execution of instructions based on this issue signal, said vector execution unit being characterized in that it comprises
