Programmable processor with group floating point operations |
摘要 |
A programmable processor that comprises a general purpose processor architecture, capable of operation independent of another host processor, having a virtual memory addressing unit, an instruction path and a data path; an external interface; a cache operable to retain data communicated between the external interface and the data path; at least one register file configurable to receive and store data from the data path and to communicate the stored data to the data path; and a multi-precision execution unit coupled to the data path. The multi-precision execution unit is configurable to dynamically partition data received from the data path to account for an elemental width of the data and is capable of performing group floating-point operations on multiple operands in partitioned fields of operand registers and returning catenated results. In other embodiments the multi-precision execution unit is additionally configurable to execute group integer and/or group data handling operations.
