A flexible processing adapter for multiple application is described. The adapter subsystem for the IBM Personal Computer (PC) is provided with a combination of new features. This particular arrangement provides significant advantages in complexity of functions performed and in functional flexibility. These features, in combination, provide capabilities to provide functions not available in other, generally comparable designs. Fig. 1 shows salient details of the adapter design. One key element of the subsystem is that it provides a programmable signal processor (PSP) in combination with read/write RAM (random-access memory). Use of RAM permits the PC to change the nature of the adapter by loading different programs into the PSP RAM.
