WebEach PE in our parallel summation algorithm in the previous section has only access to its own local memory. Access to data stored in the memory of another PE needs to be implemented by an explicit communication step. This type of parallel computer architecture is called a distributed memory system. Fig. 1.7 (A) illustrates its general design. WebSuch an interpreter has a data structure, replicated in each SIMD PE, that corresponds to the internal registers of each MIMD processor. Hence, the interpreter structure can be as simple as: Basic MIMD Interpreter Algorithm 1. Each PE fetches an "instruction" into its "instruction register" (IR) and updates its "program counter" (PC). 2.
