An apparatus is disclosed for convectively and evaporatively cooling a patient's head. The apparatus includes an upper sheet and a base sheet that are attached at a plurality of locations to form a convective device adaptable to the patient's head. The base sheet includes a plurality of apertures that direct an inflating medium from the convective device toward the patient's head. The base sheet also supports an evaporative cooling element that distributes and delivers a cooling fluid to the patient's head. The fluid is evaporated from the patient's head by the inflating medium exhausted from the convective device. The evaporative cooling element may be constructed in a variety of configurations and may circulate a variety of fluids, which may be pressurized or unpressurized. In operation, an air blower, that may also include a compressor for selectively delivering room temperature or cooled air to the apparatus, is connected to the convective device. The blower delivers air, under pressure, to an inlet opening in the convective device. The pressurized air is distributed throughout the convective device and flows to the patient's head through the apertures in the base sheet.

A method of cache mapping of compressed variable length cache lines according to claim 1, wherein said step of storing said length of said compressed cache line further comprises storing said length in a field in said cache memory. 3. A method of cache mapping of compressed variable length cache lines according to claim 1, method further comprising adding a fixed amount to said program counter wherein said program counter is used to index said cache memory. 4. A method of cache mapping of compressed variable length cache lines according to claim 3, said method further comprising comparing at least a portion of said program counter with a tag entry in said cache memory to determine whether there is a cache hit or a cache miss. 5. A method of cache mapping of compressed variable length cache lines, said method comprising: a) selecting an entry in an instruction cache based on a lower portion of a program counter, wherein said entry comprises a tag area and a data area; b) determining whether an address stored in said tag area corresponds to that of a desired cache line by determining whether the address stored in said tag area matches an upper portion of said program counter and, in the case of a match, performing steps g) through j), and in the case of a mismatch, performing steps c) through j); c) retrieving said desired cache line from main memory based upon a memory address stored in a memory address register separately from said program counter; d) decompressing said retrieved cache line; e) loading said decompressed cache line into said data area of said selected entry in the instruction cache; f) loading said upper portion of said program counter into said tag area of said selected entry in the instruction cache; g) accessing a cache line stored in said data area of said selected entry; h) passing said accessed cache line to a processor pipeline; i) incrementing said program counter by a set amount; and j) incrementing said memory address by a value held in a memory address increment field in said accessed cache line. 6. A method of cache mapping of compressed variable length cache lines according to claim 5, wherein said value held in said memory address increment field corresponds to the compressed size of said desired cache line. 7. A method of cache mapping of compressed variable length cache lines according to claim 5, said method further comprising: executing a branch, before step a), by replacing said program counter in a program counter register with a branch target program counter and replacing said memory address in said memory address register with a branch target memory address. 8. A method of cache mapping of compressed variable length cache lines, said method comprising: a) selecting an entry in an instruction cache based on a cache line index, wherein said entry comprises a tag area and a data area; b) determining whether an address stored in said tag area corresponds to that of a desired cache line by determining whether the address stored in said tag area matches a memory address stored in a memory address register and, in the case of a match, performing steps g) through j), and in the case of a mismatch, performing steps c) through j); c) retrieving said desired cache line from main memory based upon said memory address stored in said memory address register separately from said cache line index; d) decompressing said retrieved cache line; e) loading said decompressed cache line into said data area of said selected entry in the instruction cache; f) loading said memory address into said tag area of said selected entry in the instruction cache; g) accessing a cache line stored in said data area of said selected entry; h) passing said accessed cache line to a processor pipeline; i) incrementing said cache line index by a set amount; and j) incrementing said memory address by a value held in a memory address increment field in said acc
