i960® processors with extended temperature packaging.
Marketing Package Designator
|
The i960® HA/HD/HT processors provides solutions for designers that need to increase performance while containing their total embedded system cost. The i960 Hx processor series has the highest performance of the i960 architecture. |
|
|
There are three versions of the HX processor. These versions are differentiated by the relationship of the core clock speed to the external bus speed. The HA processor has equal core clock and bus speeds, the HD processor's core speed is up to double that of the bus, and the HT processor's core speed is up to triple the external bus speed. The result is a superscalar processor that can execute up to three instructions per core clock and not be starved by a slower external system. |
|
|
The Hx processor series is 100% pin compatible within the series, and code compatible with all processors in the i960 architecture. The on-chip features have been designed specifically for the embedded market segment, providing fast interrupt responses, reduced access to external memory, and integrated timers. |
|
|
The i960® CA/CF processors bring parallel computing performance to cost- and space-sensitive applications by integrating key performance system functions. Both processors are socket-compatible, allowing quick design upgrades, and are object code-compatible with all i960 architecture family members. |
|
|
The i960 CA processor was introduced as the world's first superscalar 32-bit processor developed for embedded applications. It delivers multiple instructions per clock cycle for throughput of 66 native MIPS (Millions of Instructions Per Second), doubling the performance goal of RISC (Reduced Instruction Set Computing) techniques. The i960 CF processor, with advanced cache memory design, is capable of double the performance over the CA processor in many applications. |
