摘要： Methods, apparatus, systems, and articles of manufacture to compile instructions for a vector of instruction pointers (VIP) processor architecture are disclosed. An example method includes identifying a strand including a fork instruction introducing a first speculative assumption. A basing instruction to initialize a basing value of the strand before execution of a first instruction under the first speculative assumption. A determination of whether a second instruction under a second speculative assumption modifies a first memory address that is also modified by the first instruction under the first speculative assumption is made. The second instruction is not modified when the second instruction does not modify the first memory address. The second instruction is modified based on the basing value when the second instruction modifies the first memory address, the basing value to cause the second instruction to modify a second memory address different from the first memory address.

摘要： An apparatus includes a binary translator to hoist a load instruction in a branch of a conditional statement above the conditional statement and insert a speculation control of load (SCL) instruction in a complementary branch of the conditional statement, where the SCL instruction provides an indication of a real program order (RPO) of the load instruction before the load instruction was hoisted. The apparatus further includes an execution circuit to execute the load instruction to perform a load and cause an entry for the load instruction to be inserted in an ordering buffer, and where the execution circuit is to execute the SCL instruction to locate the entry for the load instruction in the ordering buffer using the RPO of the load instruction provided by the SCL instruction and discard the entry for the load instruction from the ordering buffer.

摘要： An apparatus includes a first circuit to determine a real program order (RPO) of an eldest undispatched instruction from among a plurality of strands, a second circuit to determine an RPO limit based on a delta value and the RPO of the eldest undispatched instruction, an ordering buffer to store entries for instructions that are waiting to be retired, and a third circuit to execute an orderable instruction from a strand from the plurality of strands to cause an entry for the orderable instruction to be inserted into the ordering buffer in response to a determination that an RPO of the orderable instruction is less than or equal to the RPO limit.

摘要： An apparatus includes a register file and a binary translator to create a plurality of strands and a plurality of iteration windows, where each iteration window of the plurality of iteration windows is allocated a set of continuous registers of the register file. The apparatus further includes a buffer to store strand documentation for a strand from the plurality of strands, where the strand documentation for the strand is to include an indication of a current register base for the strand. The apparatus further includes an execution circuit to execute an instruction to update the current register base for the strand in the strand documentation for the strand based on a fixed step value and an iteration window size.
